750 should do it. I can't stress enough to get a quality PS though. There are quite a few good choices out there. If you don't have a personal preference, some names I've had some success with (by no means comprehensive): Thermaltake, Antek, Coolermaster, OCZ. Good rule of thumb is that you need to spend money here. If it's cheap, there's probably a reason, and you don't want to find out that reason when your computer starts acting flaky. PS problems are, IMO, the hardest PC problems to diagnose.
Ditto on this; power supplies are a tempting place to be frugal, but it is really no fun at all when they blow up.

I think I've made this recommendation here before, but I'm not hesitant to risk sounding like a fanboy and make it again. I strongly recommend going with PC Power & Cooling for the PS; their supplies are universally well reviewed for reliability and solid construction.

Newegg has outrageously good prices on these supplies; the 750 watt PCP&C supply is actually comparable to a lot of the far less well-reviewed supplies. I'm in the middle of replacing a dodgy power supply in my gaming machine with one of these right now. (Corsair may make a perfectly acceptable supply as well; I really don't have any experience with their PSs.)

The Thermaltake Armor/Kandalf series cases have lots of bays and can be purchased with a 25cm case fan in the side panel; this monster moves a lot of air without making a lot of noise. The Coolermaster Stacker is also a good choice; it has a ton of 5.25" bays and can be equipped with 120mm fans to cool the installed hard drives and a cross-flow fan that looks pretty effective. Both of these case series include a number of (increasingly expensive) configuration options, but the entry-level cases of both series are available for around $150 at Newegg.
