And here it is in all its assembled glory!
Noise - whisper quiet! I'm sitting right next to it right now (less than a foot away from me) with the side of the case open and I can barely hear it. The CPU fan runs at around 760 RPM and keeps my CPU at (Core 1 - 39C, Core 2 - 24C) at idle to medium load. I haven't loaded it yet so I don't know how hot it gets. Case fans are low RPM as well and produce a nice breeze inside the case while making almost no sound. PSU and video card are silent. I can barely hear them even when putting my ear right next to them (with the side of the case open).
Temperatures (idle):
CPU Core 1: 34C
CPU Core 2: 22C
Hard Drive 1: 32C
Hard Drive 2: 31C
Video Card: 52C
Case temp: 41C
My only concern so far is that the 8800GT runs at 52C idle, but the Internet tells me it's normal. Any input on this?
Performance - so far, I only benchmarked it with 3DMark 03 (because my old computer wouldn't run anything higher at more than 2fps) and it scored 38,000. Compared to my old comp's 8,400. Big boost.
EDIT: updated temperatures with all 3 case fans running
