I think the Thermaltake is pretty good for the money, but you can get a 480W PSU for $55, that's what I'd recommend. Sure, there are better brands, but for $55, you'd be getting like a 300-350W PSU, so this really shines for the money, and is pretty solid, too. Also, The setup looks, good, there are just a few alternatives you may want to at least consider.
1. The 3000+ will clock just as high as the 3200, and since the FSB will be higher, it will perform better. However, obviously there is a risk of pushing the FSB too high. If you wanna go to 2.3-2.4, then save the money and go with a 3000+. If you wanna hit 2.5-2.6, and don't want a FSB of 290 or higher, than the 3200 is a bit safer. Of course, with the $40-50 you save, you could get some nice cooling.
2. Make sure you get good cooling. 1st priority - get some Arctic Silver 5 - it's like $12, and it can lower your temps by like 15 degrees celsius over standard thermal grease. 2nd, a good heatsink/fan. I've heard great things about the Thermalright XP-90, but between that and a fan, it'll run $50 or so. A cheaper alternative is a Thermaltake Venus 12. It's $30 with the heatsink, fan, and adjustable fan controller. It's not as good as the Thermalright, but it's $20 cheaper, and still does a pretty damn good job.
3. Memory - That memory is good, but consider Crucial Ballistix also. It's rated at 2-3-2-6, but it can run 2-2-2-5 pretty easily, holding those timings all the way up to DDR438. Also, at DDR500, it's got some of the best timings around, and that's the speed you'll be running if you have a 3200+ @2.5GHz. It's $255 shipped free from their website for 1GB (they give you a 4% off coupon code if you buy a matched pair). Another good choice is PQI Turbo 2-2-2-5 Ultra series ($245 shipped at newegg)
4. Those raptors are the fastest around, but the gains of raid 0 are not that substantial in a desktop environment. A nice alternative is the Maxtor Diamondmax 10 300GB drive. It's the fastest 7200RPM drive around, not too much slower than a raptor. It's $205 at newegg, so you save $150 and get a drive that is pretty damn fast with twice the storage space as the raptors. Or, you could spend $50 more than the raptors and get a pair of the drives for 600GB! It's got NCQ for use in new mobos as well.
5. The BFG 6800 OC is overclocked by default for the same price, and has a lifetime warranty, so I'd get that over the leadtek. No matter what, though, the 6800GT is a friggin sweet card, just make sure you don't get the ASUS V9999 Gamer Edition 6800, it's just a 6800 with extra memory, not a GT, so don't be fooled.
6. You mentioned wanting to upgrade in a year or 2. If that's important for you, I'd seriously consider waiting for a PCI-express mobo. I don't necessarily recommend waiting for SLI, since it might not even be out this year, but the nForce4 boards are supposed to be available in retail by the second week of november. ATI and nVidia have made it pretty clear that the future is gonna be on PCIe, and their recent product lineups reflect this. The X700, 6600, 6200, NV41, NV45, R430, and R480 families are all PCIe only, and the only ones with plans for an AGP version are the 6600s. Graphics cards with AGP will all be just leftovers and limited runs of newer cards when you are trying to upgrade. It will be pretty much like PCI graphics cards are now. Socket 939 has so much life in it (3200 up to 4400 at least on single core, not to mention dual core compatibility), it'd be a shame for it to be limited by the lack of a good graphics slot, and the high bandwidth PCIe x1 slots for peripherals.
