## 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: The Rosewill RSV-AI01 specs say a 145mm max CPU cooler height when not using the GPU bracket. My Arctic Freezer 4U-M is 145mm high exactly, but it doesn't come close to fitting due to a critical design flaw on this case. In order to provide the 11 PCI-E slot outlets, the PSU is placed on a little shelf above the motherboard. For an SSI-EEB motherboard, this puts the PSU almost directly above the CPU, severely limiting cooling options in order to stay under the low shelf. Basically, you have to liquid cool. Now, where to place the radiator? There are no mounting holes anywhere to be seen, and because of the 8 hot swap drive bays, there's little room to work with. In fact, one is tempted to place the radiator in the space an expansion card would go on those extra PCI-E slots! Clearly this design was not thought through. The marketing photos did not make this clear to me, and I wonder if it was an intentional deceit. The only real way to run this case would be to do custom watercooling with a 2U radiator placed above the drive bays. Or drill your own radiator mounting holes into the hot swap fan enclosure. Or place the radiator in the extra PCI-E slots which were the raison d'etre of the case to begin with. UPDATE I ended up moving to water cooling, and twist-tying the radiator to the hotswap fans. Meanwhile, the power button on the case was defective, so I can only start the thing by using the reset button as a power switch. Given that you're forced into water cooling, the case ends not being deep enough. Now my PSU cables are obstructing the airflow enough that I'm getting warnings from my network card which doesn't have its own active cooling. I'm basically planning on moving this system to a Sliger case with 28" depth when I get the chance. Anyway, you get what you pay for, but sometimes not even that.
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).

## Features

- Spacious Chassis: This enormous 4U server case has capacity for 12 internal 3.5”/2.5” SATA I, II, III, and SAS supported devices.
- Expandable & E-ATX Compatible: 7 PCI expansion slots and E-ATX compatibility gives you growth options for all of your needs.
- Quiet Cooling: 5 pre-installed cooling fans provide excellent airflow and heat protection at reduced noise. 3 front 120mm fans and 2 rear 80mm fans ensure your drives and chassis avoid overheating.
- Desired Features: Front panel LED indicators for power, HDD, and LAN status monitoring allow quick, easy visual assessment. Additional utility with 2 USB 3.0 port and built-in front panel lock provides extra security for your server case.

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.
