SilverStone Technology 4U Rackmount Server Chassis with 3 X 5.25 Front Bays with CEB/ATX/mATX/Mitx Support RM400 Cases SST-RM400

ABSOLUTE GARBAGE WORTHLESS PIECE OF METAL!!!! DO NOT BUY THIS!!!! I can't believe I spent over $1000 on this junk with the rails, only to discover that the rear of the case is uneven and bent. It is IMPOSSIBLE to connect ANY PCI card. It doesn't fit. When you connect the card, the screw hole is misaligned, so when you put the screw, the card will pull out of the motherboard and won't be detected. I tried with other PCI cards and even tried changing the motherboard and screws. So the case is to blame. At this price it's a total rip-off. Oh and don't even try to contact Silverstone, you can't, their contact form is broken there is literally ZERO customer support or warranty.

this server case was a good size and fit a raid controller card 1 - 4 hdd bay. I could have installed another on the other side if I needed. I had to modify the case to accept a dual PSU, but with the minimal adjustments it worked out really well definitely recommend... thanks... Stan...

This is a great rack mounted case. You can run single or redundant power supplies, It fit my ATX motherboard and RTX card with plenty of room to spare. I have a 360mm AIO cooling system for my CPU and this case handles it with ease. Airflow is consistent and has a well defined path - front to back. Noise levels vary on system load and environmental temps. Plenty of USB ports in front, though I would have liked to see 2 CD/DVD drive bays. Mounts EASILY into a standard rack. Needs 4 screws. Can be mounted to rails to slide out if you want to go that far, however the rails are not included with the case and must be purchased on their own. If you wanted to put the case on it's side and not mount it in a rack, you can do that also. I can see myself re-using this chassis for multiple system builds.

The item was well packed, the box is not damaged, but the metal handle was dented and torn out of the casing. I suppose this is a defect.

Yes, this case is very expensive, but the beauty of a case is it can live on from one iteration of a server to the next. The 24 drive bays give you plenty of room for future expansion without having to use janky solutions because you are out of space for drives. I will say the choice of SAS backplanes did make it difficult to use a consumer motherboard since most have at most 2 x8 PCIe slots and I was already using an SFP card for 10gig fiber. I had the choice of one very expensive SAS HBA with enough ports for each individual backplane or 2 more common HBAs (LSI9300) with a riser and PCIe bifurcation. Keep this in mind when planning your build. For the record each backplane handles one row of drives (4) and there are 6 total in the 24 bay case. Functionally wise this case checks all the boxes for a sweet home lab rig with lots of storage. Just keep in mind that you will have to do some research and learn a little about server parts to have an optimal experience. One would hope that by the time you are entertaining the idea of a case like this you already have some knowledge under your belt. Also, this thing is super loud so plan on putting it somewhere that doesn’t matter, buying Noctua fans, and/or fan extension cables to hook the fans up to your MB headers instead of the backplanes. The backplanes just run the fans at 100% all the time, which isn’t necessary.
