## Description

Rosewill 4U Server Chassis Rackmount Case | 12 Hot Swap 3.5", 2.5" SATA I, SATA II, SATA III SAS | E-ATX Compatible | 3 Front 120mm Fans, 2 Rear 80mm Fans | 2x USB 3.0| Front Panel Lock - RSV-L4412U

Review: 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).
Review: This is for the Rosewill 4U Server Chassis Rackmount RSV-L4412U. The company says call support and no one can answer any questions. The say email us. Why say call us? Nothing but rude unqualified people will treat you as a fool. No technical questions can be asked because it is a call center. I want to buy extra trays and to have explained why the front panel USBs are in a single cable and why? My Linux boards need breakouts to attache the USBs. As for the actual server case, it is made well as far as the metal case. Everything fits and works so far and the trays are said to be made of ABS plastic. As long as you put 2 screws (4 are better) the hard drives should be cooled and secured properly. Lightweights will find the sealed box heavy. Remove the case from the box and it's top metal cover. Next remove the internals to lighten the case up a bit. Pull all of the trays and set them aside. Mount the power supply last! Mount the motherboard first, then the power supply. After that any trays with drives are the very very very last thing after the case is mounted in a rack. After using the trays, sometimes I need to pop a drive or 2 from the case for reasons like boot from Windows or Linux. The Linux function is useful in cloning a failing or bad drive to another. No mistakes with that function, remove all but the source and target drives! Addition 2024-11-01: I wish someone had the foresight to allow unplugged drives to still sit in the bay and not electrically plugged in. In other words, the tray would be unplugged, have its latch shut, and put back in the bay slot, but not electrically connected, then close the front door. A few more millimeters spacing would have made that possible. Thoughtless design negates this simple function. I have to remove the populated drive trays and put them where, on the floor or a desk to be kicked or knocked over? It just seems like poor engineering. These things make me wonder what other "gotchas" exist? The cooling fans will of course be replaced in time with real ones like Noctuas. That didn't matter as a pre-purchase issue. I have another identical case coming for a friend. I hope he is 5 star happier with it. Me not so much.

### ⭐⭐⭐ Review
*by S***Y on 16 March 2023*

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 techsupport@rosewill.com looks like it words and their people can check it, but they don't somehow this gets ignored. To get a response use RMA@Rosewill.com 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.
