What do you guys think of the parts list so far?
Is that heatsink overkill for this build? I won't be overclocking, pretty much just leave everything as it comes.
For graphics cards I would also consider getting an R9 290x or a GTX 970 if they're better than the 780.
Also any suggestions for a good Wireless Network Adaptor that's relatively cheap?
