I figured those ln2 systems were just for record benches? Seems like it would be silly to have to sit there and continue to pour in more ln2 if you want to use your computer. Used to run a vapoli back in the day with p4 and beginning of the 775 era. Running watercooling now, and its kinda pointless imo, except for the chipset/mosfet/ram I do like for longevity of board. But all these extreme cooling really are just kinda a waste of time as a fan is enough.
