Need a little help Basically I'm going water cooling by the end of the month and I have all ½ ID tubing stuff. I haven’t bought the hose yet as I'm away from home for a week. I was thinking of using smaller hose as my case is quite cramped already as I have four HDD and three 5 ¼ bays already in use. I really do not want to modd my case. If I do use smaller tubing/hose say 3/8 barbs will there be a massive performance difference. The stuff I have so far: 1/2" TDX Athlon64 Laing 12V-D5 Pump 1/2" XSPC R120-D Danger Den Single Bay Swiftech MCB120 "Radbox"
