Would all these components work?

Solution
MB - Changed to B150 chipset that has four memory slots.
MEM - Same specs on the modules below at a lower cost.
GPU - Higher factory overclock with the EVGA below and also at a lower cost.
CASE - On a budget I like the Deepcool lineup.
PSU - No! XFX, Seasonic, or the EVGA G2 lineup. That EVGA W1 is a poor unit. www.tomshardware.com/forum/id-2547993/psu-tier-list.html
