The above reddit build is fine, but I like mine overall as a complete package better.
Swap in a BP550 power supply. If you want to cut cost and you won't overclock, get the i5 3450 CPU.
I use this for wireless: http://www.amazon.com/dp/B002RCKDEC/?tag=neogaf0e-20
Pick whatever size monitor you want from this list: http://www.newegg.com/Product/Produ...2&IsNodeId=1&bop=And&Order=RATING&PageSize=20
64-bit Windows 7 Home Premium or Windows 8 64-bit should be used.
My main problem is that even with the $754 build i'm nearing almost $900-920 total, with a monitor & operating system haha.
