Putting this together for a friend and this is what I have so far, any recommendations? http://pcpartpicker.com/p/3B2cm
Seems pretty solid but you can go for a MSI 270 that only uses a 6-pin and you will get the same performance if you up the core speed on par with the XFX 270X. Another reason why I suggest you get the MSI card is because the CX430 only has one 6+2 Pin for graphics cards unless you want to run a 6-Pin connector with the included molex to 6-pin adapter.

FM2+ motherboard, smaller case, and R9 270.
Thanks for the help.
