So yeah still need help for cooling/case.

Are these parts all good+combine perfect harmony with eachother, any recommendations to cut prices, or improve quality of computer with out straining my budget. So far all my prices are from www.newegg.ca, iv checked others but I have really good experience with new egg!

Totally not a hardware guy so could use the help!
Thanks in advance

Looks pretty good, I'd just get this mobo (assuming no on sli since you omitted it).

ASUS P6T SE LGA 1366 Intel X58 ATX Intel

Here's some cases for you to look over
Antec Three Hundred Illusion Black Steel ATX Mid Tower
COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower
COOLER MASTER Storm Scout SGC-2000-KKN1-GP Black Steel / Plastic ATX Mid Tower
Antec Nine Hundred Black Steel ATX Mid Tower

Finally, I would consider ATI.

^Agree with jbakerlent, I would recommend ATI, as it offers the best bang for the buck right now. You could get a 4870 1GB for a lower price $155, and its performance is similar to 260gtx. Or get the 4890 for $182.99 after rebate (still cheaper than most 260gtx and offers better performance)

4870, this one blows air into your case, cheapest one:
