I'm struggling to find the right case which suits my system, yet has the space for my radiators on my current loop. I also have a Parvum ITX case which, whilst the case is great, only supports a 120mm rad. My thinking is, could I run the water cooling loop to some quick disconnects hanging out the back, then run that down to external radiators and fans? I get its more complex, and complex means leaks, but I get my cake (small case) and get to eat it (radiator support)! Has anyone tried this idea with success? What's the best way to power the fans? I've got a laptop PSU which perhaps I could wire up somehow to let the fans do their work?
