I'd really like to move my setup to a 19" rack with all of my audio gear. It would clean up my desk quite a bit and might be a bit quieter, as well as making it easier to record live shows.
To be clear I'm not building a server.
Right now my computer is in a 550D with an H110 with a full size ATX mobo (12" x 9.5") what cases will fit these components? (let me know if you need any more info)
I see no point against this ( only the looks, but hey a well done rack can look good too ).Take a look around on Newegg ( i assume you are from the US ). Check the height of your CPU-Cooler and the direction your GPU will be facing ( you might need a riser ) - watch out for vertical or horizontal IO.
All but the H100 will fit well in a server case. A 4U server case would be your best bet in fitting the H100 and getting proper air flow. I currently have a server rack (24U) housing 3 PC in my house. Works great and puts all my components in one location. Im thinking about relocating my AVR from my livingroom to my rack.
