I recently got an HD vid cam and want to do a fair amount HD video editing. I
much prefer Apple's video editing software but my MacBook pro lacks the horsepower to do the heavy lifting. A Mac Pro costs ~ $2500-$8000 and although I love Apple products, that's a bit absurd. So, I'm going to use "pc" parts running mac OS X Lion from info gathered
here.
My planned build:
Intel i7 2600k
Zalman CNPS9900 MAX Cooler
Gigabyte GA-Z68X-UD3H-B3 mobo
G.Skill 16GB Ripjaws F3-8500CL7Q-16GBRL
PC Power & Cooling Silencer MK III PPCMK3S500 500W
XFX HD-687A-ZHFC Radeon HD 6870
LG 12X BD-ROM 12X Super Multi Blue Rewriter WH12LS38
Corsair Carbide 500R (white)
All of this will be a little under $1000 after buying Lion, Apple KB and a few minor things and I haven't decided what SSD to use. Compared to the Mac Pro cost of $5,274.00

(configured to match the above or equivalent), I'd say I'm coming out ahead, plus the fact that I can OC it which AFAIK you can't do on a Mac Pro.
