no shit, skulemate. I've gone through a 1250 pump, a big arse HC, maze 3, DDen GF3 block, 10' silicon tubing, 20' of vinyl tubing, a handful of brass and poly barbs, teflon, plumber's goop, a 172mm fan and 4 120mm papst fans (not all at once), extra PSUs, rheostats and such, wire, heat shrink tubing, assorted 80mm fans, LOTS of cardboard boxes, many feet of PVC, PVC glue, WWetter, paint thinner, sandpaper, jeweler's rouge, dremel bits by the droves, foam rubber, hose clamps, zip ties, nuts and bolts, ....God, what else. It's not important... but I could have bought a freakin' Dell for the price of my cooling experiments alone.

Those of you noobs that think that you'll just buy a core, a pump, a block, and some hose are dead wrong. ....but it's fun.
