Like cyph3r said, the [H] forums being down every few hours is a turn-off. I know their forum is huge, but I remember when Kyle was doing a huge revamping of the forum to avoid down-time that now seems to have had no effect at all.
I'm really impressed with Procooling the more I'm here, though. Joe himself seems to be a really well-rounded person, doing iOpener hacks, keeping up with php updates, and building hydro-coolers in his spare time
Speaking of iOpener, it's too bad the X-Box hasn't been hacked to that extent yet (there is always PS2 linux, pre-ordering now, yay!). I would try to atleast open it up, but I'm to cheap to buy one. Then again, I know a friend who has one
