I just wanted to share a case mod which main originality is to be based on a relatively slim rackmount case while being able to host a custom watercooling loop for overclocked CPU and GPU. This comes as a follow-up of my IBM PS/1 projects. - to keep a relatively small footprint, in a desktop, under the screen, format. Yet to be able to host a 35" 21/9 screen. Rackmount case came as an obvious choice. However in terms of depth they are often too short or too long. Moreover 1U would not allow to have an all-internal loop, but 2U would be too massive. - to keep a custom watercooling loop, but this time without an external cooling tower. To do this I chose to use stand-offs and have the air flowing the bottom to top of the case. - to have a sufficiently powerful, yet relatively silent PSU... Modularity would also help with cable management this would exclude 1U PSUs.
