$797 before rebates, $728 after.

MSI Z87-G41 - Decent for the price.
Corsair XMS 8GB (1 x 8GB) DDR3-1600 - Plenty enough for gaming.
Crucial M500 120GB 2.5" SSD + Seagate Barracuda 1TB 3.5" 7200RPM - A small SSD for extremely fast boot up times and room for a few games, and an HDD for everything else.
EVGA GeForce GTX 760 2GB ACX - Good GPU for the price. ACX cooling will keep it quiet and EVGA has arguably the best customer service.
NZXT Source 210 (Black) ATX Mid Tower - Cheap decent case.
Corsair 600W ATX12V - Yes, 430w would be fine but there's literally no price difference. Better safe than sorry.
LG GH24NSB0 DVD/CD Writer - I assume he wants an optical drive.
Windows 8 Key from /r/softwareswap - This is a bit of a tricky part that will save you about $80. Basically, people that are in the Microsoft Developer Network program get free windows keys and sell them for really cheap at a community called
softwareswap. You'll need to follow
these instructions to install windows from a USB drive and then put in the key you've bought from /r/softwareswap.
If you absolutely don't want to get one from /r/softwareswap you can get a regular windows copy instead for $80 more and drop the SSD.
