Tommorow is boxing day in Canada and...  
 
Well, I have been reading about how the next gen 45 nm Intel chip seem to be running into problems and how they probably won't be ready so unless I am wrong I think I will be buying a PC tommorow...

Any problems with the build or addition? I'm a little worried about the 8800GT getting too hot. Another mobo I was looking at was the ASUS P5K-E Wifi/AP

It looks great to me.
 
I'm not a big fan on Antec, but with the bundle it seems like a good deal.
 
I don't think you need to worry about the 8800GT overheating with the 900 case, but add the optional fans if you are.
 
One thing I would add is an aftermarket tower cooler and Arctic Silver 5, a MUST if overclocking to 3.0ghz (and why wouldn't you? lol).

I'm not really sure how to OC.

I looked in the manual of the P5k-e wifi/ap board and it says that they do not recommend installing 4 gig in winvista 32 or xp 32 because it will only show 3 gig because of PAE or soemthing like that. I kinda wanna put 4 gig in my board but do I need winxp 64 or vista 64 to do that?

Change the GA-P35C-DS3R to GA-P35-DS3R. (You don't need to pay for DDR3 support.)
 
Don't worry about overclocking. My Q6600 has never reached even 90% usage in 6 months, so overclocking wouldn't bring any benefits at all, at least in my case.
 
With that video card, getting 4 GB of RAM would mean you see 3.5 GB if you use XP 32 or Vista 32. That's still a lot better than 2 GB and DDR2 prices are very low, so I'd go for 4 GB. If you choose XP Pro get the 32-bit version. If you choose Vista you might as well get the 64-bit version. The thing is, 64-bit is more future-proof and lets you use all 4 GB, but xp 32 is safer than xp 64 because lots of people use it and games and drivers are well tested on it.  
 
Since you're in Canada: www.futureshop.ca sells Z-5500 speakers for $230, regular $500; www.bestbuy.ca sells MP610 all-in-one printers at $150, regular $300.  If you're in Ottawa check out www.shoprbc.com, add the $10 CHEO donation to the cart and then the prices shown are at cost - you can save hundreds on a PC.
 
If you're worried about the 8800GT:

I agree with Noya though that the Antec 900 can take care of cooling the 8800GT, no worries. Just make sure the fan is not stuck at 29% - we've had threads about that. Or get the newer 8800GTS G92 512MB, that has a decent cooler and is faster too. Or get an HD 3870.

How would I overclock my Q6600 to 3 ghz and does it require aftermarket cooling? Noise isn't really a problem.

 
Increase the front side bus to 333 (in BIOS) to overclock your CPU to 3.0. Increase it to 400 to go to 3.6. I hit both with the stock cooler and a G0 Q6600.
 
Stock cooler is fine, but an aftermarket cooler will keep temps down. Just to note- I get rid of the thermal crap that Intel includes and put on some Arctic Silver 5.
