I have a 1U Server, its a AMD Opteron 2.0 GHz; Cooling it with the case fans is too loud, I dont mind leaving the case open from the top and running water cooling pipes to the cpu, or i've found swiftech makes a 1U water block for the proc, and it looks as that shoudl fit fine, now my only issue is which system to pick for water cooling the box, I dont want to run fans as I am going to run this in my closet, the system stays cool and runs fine with load with the system fans, what I want to do is get it watercooled. Looking for some input, thanks.
