First build, a hackintosh! Price listed below is actually more than I paid. I got a few bundle deals, coupons, microcenter's $50 off Z77 with Intel CPU deal, and lastly I converted a ton of credit card points into Amazon credit. So my out of pocket cost wasn't too bad.
Small footprint & unique, mac-like aesthetics: Silverstone FT03 mATX case.
Very quiet: Noiseblocker fans, WD green HDDs, SSDs, PSU is fanless until high draw, ASUS DCII card is very quiet.
Good performance: i7 3770K OC'd to 4.2 GHz, GTX 670 card with mild OC, 16GB ram, 240GB primary SSD, Venomous X cooler. EDIT: dusted, improved cable management, switched fans around, etc. and in Windows running Prime95 on all eight threads my max temps decreased to 57°C! Yet in OS X, it reaches 64°C? Odd. Well within my preferences though.
Build status: complete!
