Oh yeah. All that should be fine. I've got a 700w Coolermaster and if I bought a third internal drive it would be the same as the other two (7200rpm Barracudas) so it wouldn't be any noisier than those although my E drive does make a bit of a clunk when it first spins up which I have to fix because it SHOULD be on all the time. I may even get a 10,000rpm now that I know they exist and use that as my C drive instead. Still not into dropping the cash on an SSD. Seems unnecessary.
Oh and the case has plenty of room. I think I still have three open drive bays. It's designed to take a RAID set up. Very nice case. Zalman z9 Deluxe if anyone is curious. If you can find one it is the shiz.
And now that I think about it I believe there is a sixth drive bay at the top for an SSD. Came with lots of ultra quiet fans too and I've got three more fan mounts available.
