Sure. I have to buy everything (monitor, keyboard, etc.) because right now I'm still using a laptop I got in 2007 that I overly upgraded. But if I focused on the same components in MIB's link (thanks by the way MIiB, it had the exact MB I was looking for as I hadn't looked on Newegg) it's going to be between probably $430 and $500 as I haven't settled on what case I want.
The following prices exclude discounts.
CPU: Intel G630 - $67.99
GPU: EVGA Geforce GTX 560 SE - $129.99
Mem: PNY 8GB (2x 4GB), DDR3-1600MHz, CL9, 1.65v - $42.99
MB: GIGABYTE GA-H61MA-D3V - $69.99
HDD: WD Caviar Blue, 500GB, 3.5", SATA 6Gbps, 7200RPM, 16MB cache - $69.99
OD: LG Internal 24X DVD Writer, SATA - $17.99
Total: $398.94
Including everything I need, it should be under $800 excluding S/H. The monitor and OS are the most expensive parts of my build.
