Rosewill 4U Server Chassis Case|Supports up to 4 GPUs|8 Hot-Swap 3.5"/2.5" SATA/SAS up to 12Gbps|E-ATX Compatible|3x 12038 Hot-Swap Fans,2 Rear 8038 Fans|USB 3.2 Type-C|With Rail Kit-RSV-AI01

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).

I already bought 4 cases from Rosewill. I bought in past the R4000u, L4500, Z2700 and the L4412. Rosewill made great product. The RSV-R4200 is great. I got enough room for an ATX motherboard and multiple HDD.

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.

I am actually writing this review in hopes that Rosewill support sees this and lets me know where to get spare parts. One of the hot swap bays/modules in my RSV-L4412U is bad, and tech support ignored my email and the phone line hung up on me. Where can I get a spare? I would advise against getting this unless Rosewill demonstrates publicly that they respond. UPDATE: Also this case came with 3 faulty SATA cables. I didn't even attempt to RMA these, I simply used spares I had on hand. Don't call, their phone number in the manual, simply hangs up after a few minutes on the phone and provides no option to hold. The email in the manual [email protected] looks like it words and their people can check it, but they don't somehow this gets ignored. To get a response use [email protected] and even then take response with a grain of salt because they have crap internal communication. The spare part number for the hot swap module is: RSV-SATA-Cage-34 There are retail and RMA versions of this part. I am not clear on the exact difference, but RMA representatives promised me a replacement in 1-2 business 2 weeks ago and I never received any update after that, then I learned they were out of the RMA version. To be fair to them they said there might be other delays but I expected some communication, and that team ghosted me. Eventually a Rosewill representative did call me but only because of this review. They wanted to make whole situation right and offered me the retail version of the part. This rep explained the inventory difference, was puzzled about the non-responses I got but recorded (and verified them, I had all the ID numbers and timestamps). I suspect this is a different team that is less dysfunctional. Don't use this case unless you have a very reliable checksumming system on your data. I am using ZFS and its checksumming was key in identifying the faulty cables and faulty hot swap module. It is still cheap for what it is, the next cheapest solution is north of double the price. So if you can reliably find silent data errors and have a willingness to troubleshoot this can be made to work. I moved this to two stars, for now. Since my complaints are mostly around service if I do get the replacement cage I will move this review to 4 stars, because it is now clear they are trying but have crap systems in place now. I can't give 5 stars, it has been more than a month in total and they still haven't gotten me a spare. Update 2 This review resulted in a call to me, that resulted in a replacement for the faulty part being shipped to me. This took far too long and critical mismanagement like this is part of why I was avoiding NewEgg. Amazon isn't great but at least they respond, and now this replacement shows up in a NewEgg box?! Like they are proud of this level of service. If I had known newegg was involved. I wouldn't have ordered this to begin with. I had been boycotting newegg because of them having ripped me off a few times and likely criminal levels of shenanigans. I can't go higher than 3 stars knowing this put money into the hands of people I specifically chose not to. I don't think I will be ordering anything from NewEgg or Rosewill for several years and if you do be ready for a hassle if anything goes wrong.

This was set up as a Jellyfin Server. Glad i picked this case, but i had to make a few mods. Starting in the front: Airflow was restricted in the front, so I opened it up. I replaced the factory fans and installed 2 each Rosewill RFX-120 fans (and their speed controllers) in front but kept the 2 each Rosewill chassis factory 80mm fans in the rear. I cut away the restrictive plate both front and rear and put in fingerguards. Motherboard: MSI Pro Z790 wifi DDR5 On top of the CPU (I5-12600K) fit a Thermalright Assassin 120 Refined SE, which fit in just fine with about 1/8" of clearance. The hard drive rack isnt shown in the pictures, but full size drives DO fit fine with a little creative forethought with cable management in mind. Get 90 degree fittings for your USB 3.0/3.1/3.2 connections on your motherboard so you'll clear the hard drive rack. (HEY ROSEWILL, BRING BACK THE RFX-120!!!) Power Supply: you'll need a power supply that will run your 14 hard drives (if you're going with that many) I'm only running 12, so I went with a Cooler Master MWE Gold 850 - V2. I also had a battery backup capacity to keep in mind, so while a 1300 watt PSU would have been nice, it was out of the question. It has 12 SATA power connectors. Rivets: These were trash from the factory, I suggest replacing them and doubling the amount. 12-14 HDDs weighs a lot and 4 rivets don't cut it. That's just bad design. All of the rivets were already loose when it arrived, and nothing had been installed yet. The factory likely used pnumatic rivet guns on an assembly line type environment. I ended up replacing all of them with 1/8" and added 2 extra on each side for added rigidity. The brackets that the hard drive rack screws into stripped out after only 3 or 4 removals. I'll be getting some threaded sockets in there soon. Rigidity Bracket: There's a bracket that goes over the power supply, with the Assassin cooler in the way, theres really no way for it to fit and be functional without moving the brackets. So I won't be putting it back in. The case sides aren't bowing out any amount to need it however. If I were designing it, I'd have put it closer to the center anyway. A bit unnecessary. USB Cables are too long. Most motherboards have their ports about 6" away, but they have 18" of cable in there to manage. Why exactly? Make them 10 or 12". Case Integrity: Solid case, good thick steel. Not flimsy by any means. Spot welds are solid, heat applied coating was well done. Resistant to scratches, as I did have this on the workbanch while I did some grinding and cutting work on it and I was NOT gentle with it. Overall, a GREAT case, but for something that's going to generate a lot of hard drive heat, a little more thought should have gone into airflow and dissipation, especially if going into a server rack.
