Updated from this first build
Added new CPU/mobo combo to overclock system to 4.5GHz. I mainly use the desktop for CAD modeling software and some gaming (League of Legends).
CPU: Found an awesome deal at the local Micro Center on the new Haswell-refresh "K" unlocked multiplier CPU. Currently running at 4.5 GHz air-cooled.
CPU Cooler: Finally installed the Zalman OPTIMA with the included thermal compound sample.
MOBO: Purchased CPU/MOBO combo at Micro Center for $100. First time overclocking the CPU through the BIOS.
Currently waiting on the new TP Link TL-WN722N, as the older TL-WN725N model is not compatible with my Comcast wireless gateway.
NOTE: Improved cable management with new build, as compared to my first desktop.
UPDATE: Added Asus DVD burner for $16
