Will this system work?

Solution
In future, please list names rather than links..... no need to give everyone RSI doing a click fest :)

Decent Case..... other one I'd look at is the Phantekls Enthoo Pro....more features, cheaper.

Consider a Z97 MoBo

A 550 watter works for a single R280, 750 watts for two .... more if you want overclocking anything .... Corsair RM or XFX Core Edition on budget.... Corsair HX, or EVGA SuperNova if want 1st tier ... Seasonix X if want best.

Consider The WD Red's Ranking here (30th)

I'd consider swapping the SSD + HD and the 280 for a 290 and SSHD which would be cheaper than that HD.
