Silverstone RM52 - 5U

Ever since SilverStone entered the realm of rackmount server cases with radiator compatibility, the company has consistently sought ways to improve cooling performance. Its predecessor, the RM51, boasted 2 x 180mm fans, which provided exceptional intake performance. This innovative design allowed for the incorporation of a 360mm radiator (dual 180mm) and even featured an adapter bracket that facilitated the use of a 360mm radiator (triple 120mm). However, the successor, the RM52, maintains the same 5U form factor and internal structure, ensuring compatibility remains intact. Nevertheless, it stands out from its predecessor due to a significant upgrade. SilverStone's pursuit of enhanced cooling performance led to the inclusion of an additional 360mm fan / radiator bracket in the RM52. This groundbreaking innovation now enables users to utilize not just one, but two 360mm radiators to perfectly serve systems with dual CPUs. Review: Plenty of room for activities! - 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. Review: This case is rad! - This thing is rad. I wanted to put my gaming pc into my server rack and this thing was able to fit my RTX 4090 and iCue Link Titan 360 water cooler with room to spare. I was worried about heat, but so far so good on the temps. I did replace everything with Noctua fans to keep things quiet. I did have to do a little modding of the case to get the radiator to attach to the included water cooling bracket, but it was easy. Paired with Silverstone server rails, the installation into the rack was easy and the fit is perfect. It slides like glass. The only thing I don’t like is the front LED activity lights are waaaaay too bright. But you don’t have to connect those to the mobo if you don’t want to. Other than that, this case is awesome.
