@eNkrypt: I went with 4 x 100mm Scythe Slim (2000RPM) fans, mounting two at the bottom of the rad & two at the top of the 600T case, where the grille-insert removes. I have them in a push-pull arrangement and have noticed that there is a minus 1-2 degree difference if the fans pull air in from the top as opposed to push it out. This difference is negligible given I'm using an H100 to cool the cpu. I'll start worrying about 1-2 degree differences when I get a chiller
@fester99: The first couple days were filled with ktext panics and me not understanding them - but that only required a few gallons of coffee and several packs of smokes to become comfortable with. If this is new territory, it's going to seem daunting. This was my first crack at the cat. I built my rig this weekend, played with it on Windows (yawn) briefly - and went right to hackintosh-ing. I just installed OSX on my 240GB Corsair SSD from an 8GB USB Lion Installer, today. WOW. The entire installation took about 5 minutes. No kidding!
You won't get any 'easy' answers at the forums, trial and error seems to win the day. Again - I'm using an unsupported X79, however if you use an X58 or Gigabyte mobo - those are the setups they've catered to. The only way i could boot my southbridge (IOSystem) is using the dsdt=null flag. BUT! I digress - I'll post that in the tony mac forums!
The short answer: It was hard for the first 2 days. The last 5 minutes was a cake-walk!
