CPU: Up to 4.2ghz at 60C load. Will probably leave it there to keep temps and noise down.
HSF: 31C idle and 58C under load (IntelBurnTest/Very High) at stock speeds.
MOBO: BIOS is easy to navigate. Overclocking relatively simple.
RAM: Fast & cheap.
SSD: Cheapest I could find with consistent good reviews at the time.
GPU: Scored a 10,050 in 3DMark11 Fire Strike. Runs ~60C in BF4 ultra as well as Unigine Heaven and 3DMark11.
Case: 200mm fan in the front!! I tried putting 80mm fans in the back but they were too loud and did not push much air. Zip tied the Noctuas to rear and side and airflow improved drastically.
PSU: Got a good deal in my opinion for gold rated PSU.
OS: Free through Dreamspark/upgraded to 10.
Case Fans: From a previous build. Very quiet and lower temps a few degrees better then stock fans. Paid ~$20 each. They are both exhausting to not compete with gpu. Providing good airflow and not nearly as loud as the 80mm fans I had in there.
