Don't cripple an expensive build with a WD Green drive. And you'll probably need larger than a 2TB for mass storage.
yea u are right. Would this be a better build? http://uk.pcpartpicker.com/p/2HZJ5
Seeing as almost 1/2 that cost is peripherals (monitor, keyboard, etc), that's not too bad.
I'd probably go with a different PSU. Seasonic, perhaps.
