4U Server Chassis Rackmount Case | 15 3.5" HDD Bays | E-ATX Compatible | 6 Front 120mm Fans, 2 Rear 80mm Fans | 2X USB 3.0 | Front Panel Lock and Key | Silver/Black - RSV-L4500U

Fits an Asrock Rack X570D4U, Ryzen 9 5950x + Thermalright Peerless Assassin cooler and a 5090 FE perfectly. Plenty of room for longer PCIe cards, but there really is not enough enough room for power connectors on graphic cards. You will need some right angle adapters on larger cards if the power connector is not already at an angle, like it is on the RTX 50 Series Founders Edition/Pro RTX 6000 cards. There is a support bar that goes across the center, but this was easily removed for space. Included fans are not PWM, but are quiet and functional. Requires two 4-pin molex power connectors for each of the drive bays and the rear fan (7 total), but could get away with a couple of splitters if using SSD's instead of power hungry HDD's. The drive bay power connectors are wired parallel and feed all of the drives (so two 4-pin molex in parallel will feed four drives).

This is a solid, well built budget rack mount server chassis. It's important to understand what you're getting here. So long as your expectations are appropriate, these chassis offer excellent value. First off, these are no SuperMicro. The target market is not enterprise companies. If you want a complete SYSTEM - and by that I mean, chassis, rails, etc. that all work together seamlessly - look elsewhere. But if you are willing to overlook a few potential warts, this is a great value. Now, let's first clarify some typical, appropriate use cases for this chassis. For starters, I bought the RSV-4500. This chassis comes with 8 fans and holds up to 15 3.5" hard drives. The hard drive caddies are up front, and mean there's air being pushed across them, and then air is pulled across them as well by the next set of fans, located about 1/3 deep into the case (measured front to back). The distance between both sets of fans is ~9". This leads me to suspect this amount of cooling is overkill for most disks, even with 5 of them per cage / per set of fans. The fans are 120mm. There is a sister case, which is Rosewill model RSV-L4412U. The only difference between them is the RSV-L4412U model has 12 hot swap bays and is missing the 3 front-most 120mm fans found in the RSV-4500. The hot swap bays provided with the RSV-L4412U model are 3x RSV-SATA-Cage-34, a 4-bay 3.5" drive cage made of plastic and have some questionable design characteristics. They retail on Amazon for ~$80 each + tax. If a budget hot-swap rackmount chassis is your goal, the RSV-L4412U is an incredible bargain. If you were to purchase the RSV-4500 for example, and then purchase 3x of the Rosewill drive cages, you would spend substantially more money than if you simply bought the RSV-L4412U in the first place. If you are more interested in getting the best overall combination of number of 3.5" hard drives, hot swap drive capability, and a good quality chassis, you are better off going with the RSV-4500 and separately purchasing 3x 3.5" drive cages manufactured by Norco or SuperMicro. Several independent tests have shown these drive cages to be among the best at keeping 3.5" drives reasonably cool. Avoid Icy Dock. iStarUSA used to produce good quality drive cages, but their current offerings are either flimsy and/or have poor drive cooling, and should also be avoided if you would like to ensure your drives don't fail prematurely due to constant overheating. There is one other option for a 15-drive bay setup. That is to go with the RSV-4500, not purchase hot swap drive cages, but remove the front fans. In this configuration, you still take advantage of the air filter built into the front of the flip down case fascia, and it is possible to position the drive inserts that come with the RSV-4500 case such that your SATA/SAS connection is facing rearward, while the clips to remove a drive and replace it when necessary are pointed forward. This will allow you to close the fascia and hide your bare drives, but access them easily when necessary. This approach is not for everyone, but it is a budget-conscious solution that will provide you with up to 15-drive bays in a well-cooled chassis, in spite of removing the front fans. With your drives installed in this manner, they will still be ~4" from the 3x 120mm fans still installed in the case. For most people, with most hard drives, this will be more than adequate air flow to keep your drives reasonably cool. To re-cap, there are several options for installing a good sized bank of 3.5" drives in this case, and its design offers considerable flexibility. One area that is a negative, is the documentation for the chassis is mediocre at best, and poor in some respects. For example, it fails to explain the fact that in order to depress the tabs that release the incumbent hard drive cages in the RSV-4500, you must first remove 1 or 2 screws for each cage that holds it in place. Once you have done so, the act of removing the drive cages requires one to simultaneously push down a couple of metal tabs on top of the drive cage, and apply force from the rear of the drive cage pushing it forward. Then, it will release out the front of the case. Furthermore, these acts require the removal (or at least sliding back) the top case cover. This latter point is noteworthy if you plan to install the chassis in a server rack and anything is installed directly above it. This, in turn leads me to my final point; the rails. I purchased the set of rails manufactured by Rosewill and compatible with this case. These rails are not included with your purchase of the chassis, which is a common issue with budget rackmount chassis. Unfortunately, the Rosewill rails use an old, rudimentary design that has fallen out of favor with most large, mainstream server chassis manufacturers, and for good reason. There are a lot of variety of server racks on the market now, and I found the Rosewill rail system would not install properly on my wall-mount server rack from StarTech. Specifically, the outer rail - where it wraps around the front and rear of a 4-post rack - was 1/8" too wide. This resulted in a narrowing of the space between both inner rails of 1/4", which was enough to make it impossible to install the Rosewill RSV-L4500 chassis in the server rack after attaching the inner rails to it and attempting to connect it with the middle rails on the rail system. Careful investigation after it became clear the unit was not going to fit into the rack revealed the flaw in the design of the Rosewill rails. I then experimented with a set of 3U/4U SuperMicro rails that use a more modern rail design, but I ran into the opposite problem. This combination resulted in an extra gap between the sides of the RSV-L4500 and the outer rails attached securely to the rack. I could have attempted the use of 5mm spacers, but this would have made the process more complicated by requiring 5mm longer screws. Furthermore, the rail screw holes in the SuperMicro inner rail did not align well with the side of the RSV-L4500 and it's pre-drilled rack rail mounting holes, meaning it would have been necessary to tap drill out multiple new threaded holes in the case for the purpose of utilizing the SuperMicro rail. In short, the LSV-4500 does not lend itself to universal rails (I also tried a set of StarTech rails, which also had alignment issues), due to the uncommon width of the server (it is rather narrow at 16.8" wide). That being said, if your server rack is designed in such a fashion that the Rosewill rack rails are able to wrap around the edge of the server rails without pushing back into the interior of the rack, as was the case for me, then it may be an option for you. Bottom line is this chassis is a solid budget choice, but it does have some drawbacks, depending on your needs. If you're willing to live with a bit of inconvenience and have a means to support it well enough in your rack (weight with all parts installed and 15 drives will be ~ 60-75 lbs.), it is a solid, economical choice for a large 3.5" drive system for a home network NAS or media server. It's not perfect, but it is a good overall value. YMMV ------------------------------- EDIT 01.14.2022: In my original review, I inadvertently failed to clearly explain an important step if you wish to front-load your drives into the LSV-4500 case. It's a big enough pain that I should have provided more details in my original review, but here goes.... The LSV-4500 is designed such that you must insert and remove your drives from the rear of each of the three (3) groups of five (5) drives. That means in order to exchange a drive or install a new one you must do the following: 1. Pull the chassis out of your rack. 2. Remove the chassis lid. 3. Release the drive cage and slide it partially forward. 4. Reach to the back of the drive cage, pinch the tabs for the drive you need to remove, and slide the drive rearward. 5. Remove the attached SATA and power cables. In my original review, I mentioned there is an alternative approach where the drives may be mounted from the front. What I neglected to mention is this method involves minor hacking of the drive cages. Specifically, there are small, metal tabs toward the front of the drive cage, which are designed to stop you from accidentally sliding a drive too far forward and into the path of the front fan blades. So, if you want to be able to front-load your drives you will need to bend these tabs inward so they are flush with the inside side walls of the drive cage. It's not particularly difficult. This can be accomplished with a good set of ordinary pliers or a vice grip. A downside of front-loading your drives is it also means getting rid of the front mounted fans. There's really no point in keeping that in this configuration, as you'd have to remove them in order to get to the drives, defeating the purpose of having them be accessible from the front of the chassis. The upside is of course it means there's no need to remove the top of the chassis and manipulate the drive cage to remove or add a drive. You may think of this as a "budget hot swap" option if you like. Personally, I don't recommend going that route, but if it suits your needs it is an option. <b>SuperMicro Drive Cage Swap</b> I've since found there is yet another option if you're interested in tinkering with the RSV-4500. It turns out that SuperMicro 5-disk mobile drive cages happen to fit very nicely in lieu of the stock drive cages. Remove the stock drive cages, insert the SuperMicro mobile drive cage with the LEDs at the top, and secure the SuperMicro cage with 2 screws on top and/or bottom. The cage will be firmly in place, and now you have just added 5 hot swap bays to your chassis. Next, you have a few possible configurations for this mod. You may then use the SuperMicro drive cage as a hot swap drive cage if you'd like. There is barely enough room to leave the 92mm fan on the rear of the SuperMicro drive cage in place, however I recommend removing it. I conducted some tests with an air velocity tester used by HVAC technicians to measure air speed and throughput, and I found with the SuperMicro 92mm fan blowing into a 120mm fan in the middle drive cage, it actually reduced the amount of air being pushed backward in the case (though I was not able to measure whether or not it improved the hydrostatic pressure). The problem is there's barely any space between the fans. You can move the middle fan rack back further by about 1/2" via an extra set of screw holes in the side of the chassis, but either way we're talking about less than 2" of clearance between both fans. Therefore, i recommend removing the SuperMicro 92mm fan from the back of the S.M. drive cage if you implement this design in your chassis. This also solves the problem of trying to route all your SATA cables from the back of the SuperMicro drive cage backplane to your motherboard without getting them in the way of the fans. <b>Other Information Tid-bits</b> 1. You must use the stock drive cages if you want to use the front mounted fans. The fans are bolted into the fascia of the drive cages, and these are in turn designed to be recessed into the front of the case such that the locking front panel is able to close properly. 2. There is an air filter built into the lockable front panel. 3. The middle fan rack can be removed. It may also be adjusted very slightly by moving it back about 1/2" in the chassis, by mounting it with an alternative set of holes on the side of the chassis.

It’s a good case if you’re looking for something like this. Looks clean, metal is a good thickness, build is solid and stable, it has a lot of room, and the included fans push good air and run pretty quiet. There is basically no built in cable management though so get cable ties. The two front fans use 4 pin connectors but I needed to buy extensions to reach the motherboard. The three center fans use molex connectors but can daisy chain so you only need one free molex connector. It’s overpriced for what it is compared to a normal desktop case, but I got it on sale for $150 so I’m happy with it.

This is not a high end case. The metal is flimsy, the wires for the front panel are in the worst spot - right next to the hard drive case and they run when I drop the hard drives in. Everything is screwed together, there are no quick release features or drive cassettes to make removing drives easy. While you can fit a full size ATX motherboard in here, you will not fit a long video card. The drive bay also sits right where most motherboards have the 20pin connector for USB, I had to get a 90° adapter. It does come with 3 fans installed. I don’t think they are very loud but my server is in a utility room. I was able to place 6 spinning hard drives and an adapter for 2 SSD’s in the drive box. I also have a blue ray drive in one of the 5.25 bays. It gets the job done. I wish it was a little more sturdy, a little more room.

Really junky construction. The SSD clips snapped off when trying to eject the SSD trays to put in drives. They are literally designed to pinch and slide out and they broke with reasonable force to eject them. The case doesn’t even fit properly in my rack. The screw holes are way too close to the giant handles on the front such that my mounting screws for my rack don’t have enough clearance to go in and it resulted in stripping my rack’s screw holes due to the shear force of trying to drive them in at an angle. Overall I regret my purchase and would advise against anyone else buying this case.

I was really concerned about buying this based on some of the reviews. And so far, after about 6 months of using it, I'm really happy I went this route. Everything arrived as described, the quality is spot on what I would expect for the price. The assembly was easy (if you know how to build PC's) and everything fit as expected. I did have to use a low profile CPU cooler so don't expect a Hyper 212 evo to fit. This greatly expanded my NAS storage and Plex server capabilities by being able to have up to 15 drives. Was also nice to be able to use a standard power supply with it.

I was looking for some cases for a budget server rack build. I ran across this one. Fit the design, and made by a manufacturer I was familiar with (unlike other manufacturers that just string a bunch of nonsense letters together). Case was decent enough. A couple of quibbles. 1) The cross bar is highly unusable if you are using anything substantial for a CPU cooler. But, it is removable, and doesn't seem to provide any real benefit anyway. I realize this is for GPU bracing, but really, you don't want / need this anyway for that purpose. 2) The intake filter is not easy to get to and kind of defeats the purpose of serviceability. To get this thin, under performing filter out of there to service, you have to literally take the fan bracket out of the case. This is not easy feat. Not sure why no one thought this a problem during design. I personally removed it completely to ensure good airflow anyway. The filter restricts a lot of it. 3) The handles don't seem very strong. Personally, I wouldn't allow the full weight of a built server to be suspended from these handles for any length of time. They likely will crack or break completely. They are good for sliding the case forward for rack removal though. 4) Case came with pre-installed MB standoffs. If you want to thread in more, this becomes an issue. I bought 5 of these cases. And, on each and every one, the extra standoffs (for full ATX installation), were not threaded at all. Which means you have to carefully thread in the standoffs into the unthreaded holes slowly, so they create a thread in the (thankfully) soft aluminum. This works, but geez, why aren't the holes pre-threaded? All in all, good budget rack mount case when money is tight. Just be aware of the pitfalls.
