My Critiques:

1) Cheap MB - would recommend ASUS, DFI, and maybe BIOSTAR as a cost-effective board. (I hate Gigabyte, but I hear they are good...)
2) AMD CPUs are low-performing chips, I must admit. If you want pure performance, go for a Core 2 Duo. Besides, I wouldn't recommend the Windsor cores either because they are power hogs and thus heaters... (not as bad as the old P4's though...)
3) PSU: I hate Antec PSUs, but hey, as long as that has a good amount of amps on the 12V rail.

Notes: I would recommend the BE for processor. >
I would suggest picking up a good AM2+ motherboard so it'll be Phenom ready, (which also supports crossfire) even though it'll cost more. The K9A2 CF-F is around $90 and it's Crossfire with the 790X chipset, meaning it's AM2+, and PHENOM READY.

HOWEVER, BEWARE THAT THIS SPECIFIC MOBO WILL NOT SUPPORT 125W PROCESSORS, MEANING IT WILL NOT WORK WITH YOUR CURRENT 6400+, so maybe a 5000+BE... an overclocked 5000+ is much cheaper and faster anyway.
You can try to find other 790 chipset motherboards, but those will be a lot more expensive.

It doesn't make sense to get an AM2 only system now because they won't have HT 3 and a lot of features the new Spider platform motherboards do. Aside from that, your build looks pretty solid. I would get 4GB RAM, but that's just me.

Okay here's my critique, so do with it what you will.
HD - okay
DDR2 - okay, better if it's the CAS4 stuff (4-4-4-12)
PSU - I'd refrain from the BASIQ one and get one of the ones below that are at the same price and provide more Amps on the 12V rail(s):

$70 - $30 MIR = $40!!! Can't beat at this price for 30A on the 12V rail(s)! Has 3A more than BASIQ and is more power efficient! 3 yr. warranty, which is quite nice

$75.50 - $10 MIR = $65.50 Has 33A on the 12V rail and is power efficient too. 5 yr. Warranty, which is really nice

Mobo - I'd change from that one as "Loser777" stated to the one he linked, unless you want to spend more. It can be had here for about $10 less, with shipping:

CPU - I'd go with the 5000+ BE instead of the 6400+. All you have to do is change the muliplier and "BAM" your at 3 gHz!!! You can go farther, but that is where I'd go, since you wouldn't have to mess with any other settings, usually.
$99 shipped, just need to add HSF and your done!

Case - Looks like a decent one and not too expensive. Cooler Master has good ones too. I'd look at the CM 690 for equivalent build.
$86 - $35 MIR = $51!!! Nice buy too!

CPU HSF - Okay, but get the AC Freezer Pro 64 for $30 less. It runs cooler than the one you selected. Here's a link so you can see in the chart where your Rosewill stands and where the AC FP64 stands.

So you can decide if you want to spend $30 less and get better cooling or not.
