420 watt PSU with 8800 GPU?

[Retronym]

Im planning on getting a LAN PARTY SPECIAL (amd shuttle system from cyber power pc). They only come with a 420 watt PSU. I am worried it won't be ample power for an 8800 gpu and raptor hard drive. Here are the specs of what I plan on getting:

X-QPack case w/420 watt PSU
Biostar Nvidia 6100 MOBO
1GB Corsair DDR2/800 PC6400 XMS w/ Heat Spreader
1 8800GTX
1 WD 74GB Raptor HD
1 generic optical drive
onboard sound
AMD socket AM2 Athlon 64 X2 4600+ dual core CPU

Can this system power any of the 8800 series GPU? Im hoping it can, since cyberpower lists all 3 cards as an option (though no sli of course).

If not, what would be the best video card possible?

I don't think that is going to be enough, a nice Corsair 520W will do the job.

Not even close: That's the Ass-pire 420w that got like, a 0 at Jonnyguru. Doen'st even come close to doing "420w"

Does a 8800GTX even fit?

I honestly have no idea. Cyberpower uses a bulleted list format to add and change computer specs to your build. I would assume they would only include applicable choices, but then again, they may only catch problems after point of purchase. Maingear computers has a similar form factor called the x-cube, that does feature 8800 gtx as an option, though not in SLI. It runs off of a "maingear 750 watt PSU". Using that as a general basis of comparison, I assume it could be possible albeit cramped.
