I used to run a modified vapochill a few years back before I went to watercooling and a pelt setup.. Ive had a few extreme cooling based systems but Ive sold most now and am more into the SFF and Linux boxes these days.
If you get any issues with it or want to modify it I know theres a few guys who run them over at the forums im a moderator off that could help you
