Silverstone Technology RM51 5U Rackmount Server Chassis with Dual 180mm Fans and Enhanced Liquid Cooling Capability, SST-RM51

Solid case. Well thought out layout and sturdy. Also big enough to mount a gaming GPU!

Excellent PC case for an entertainment center rack. The front IO panel is easily accessible and the large power button is a nice touch. The length is not too deep either, even with the rear fan cage attached to the back, but it can still comfortably fit a 5070 RTX AND a liquid cooling radiator with all the included fans. Very thoughtful design. The only downside is the sliding rails accessory (RMS05-22) is made for deeper racks so I had to go custom on the supports as this case is very heavy.

Everything came together wonderfully. All screws and hardware were present and plentiful. Some of the bags did have labels in Chinese but it wasn't a hindrance to the build process at all. It's obvious which screws go where. Specs below since that was what I wanted to see in the reviews before getting this case, to make sure everything will fit: - Asus Z790 proart creator - Asus Ryujin III 360 AIO - Asus Nvidia RTX 4090 OC TUF - Corsair HX1500i - 2x Samsung 990 PRO - 2x SSDs, 2x HDDs - 2x 80mm, 1x 140mm Noctua fans for the case - 4x Corsair Dominator Titanium I ended up taking the handles off because they will prevent the case from being pushed all the way into the rack when the rails are put in, but its still easy to pull out/push in with the little two-finger slot in the middle. And I looked everywhere for the size for that rear fan but could only find one mention of 120mm. It does have the screw holes for 120mm but it is spaced for 140mm and has the holes for that as well so I had to order that after finishing the build. There isn't any hidden cavity to hide the wires but there is plenty of push-pull air going through all the components with all the fans mounted. The 4090 power cable has plenty of space for a graceful bend even with the HDD plate added on top. This mobo didn't have the header pins for LAN activity but I don't care about those, everything else worked out perfectly. With all 13 fans at full power on startup it is still very quiet, my switch is louder than that at idle. This is the rack mounted pc gaming / workstation solution that you're looking for. I don't think that any of the 4u options out there would have sufficed for the massive 4090 without an aftermarket fire-hazard 90-deg connector or a dangerous bend.

I wish this was around when I got the RM42-502 case, which while it was a great case, with a 3090TI it got hot and there was no way around it. When I saw this as a 5U case, I got excited. Then I saw the exterior 2x 80mm fans that mount above the slots. I tried doing this with some tiny (40mm?) fans on the RM42, but didn't really work. I'm thinking this will. Plus those giant 180mm fans in the front. My AIO water cooler is a 240mm x 120mm (2x120mm fans) solution, which I mounted covering 2/3 of the 2x180mm fans, while also still having my 120mm fans mounted on the back side; so it's a sort of push-pull configuration. But, about 2/3 of the left fan has a straight shot to my GPU. The 2x80mm fans transferred from the previous case, and those pull the air out from above the GPU. All in all, a well laid out case. PLENTY of room. The bad: It arrived with a slight bend in the back. A bit of effort and it's fine. Edges have some sharp to them too, so just watch what you're doing. Expensive for what it is, but what it is, is very niche market and there are far worse options ;)

Ive been wanting to rack my gaming PC for a while but i was worried that i wouldn't be able to fit everything into a 3u or 4u server chassis, so when i found out about this 5u case I bought it straight away. The case itself is very sturdy and it comes with all you would need to build any PC you want inside of it, also comes with legs so that you can stand the PC on its side which i used for a while while i waited for parts. The rm51 is a good product and it does its job, my only issue with it is its price but with this being such a niche product i cant complain much.

It's nice to see that they take the time to mask off parts before painting. I need good RF shielding and paint would hurt that. I also plan on mounting the removable drive bays where the power supply goes and then place the power supply inside. It looks like it was made for this, but I can't find a part number for a bay for it. The main downside of the 5U case is that it's heavy. I also went with the 5U size in order to fit the huge Air cooler for the CPU.

Solid quality, easy to build in, fits everything (4090) very well.

It would be nice if the fan was quieter
