PARTS NOT REQUIRED: keyboard, mouse, speakers, monitor

PREFERRED WEBSITE(S) FOR PARTS: NCIX

COUNTRY OF ORIGIN: Canada

PARTS PREFERENCES: shown below -> not dead-set on anything if there is a good reason to change

OVERCLOCKING: maybe, need to save money for a cooler SLI OR CROSSFIRE: maybe, farther down the road ex. in a years time

Basically just asking if all this stuff will work when i put it together! Or if there are better options available. Power supply I know is overkill, but I would like to use it in future builds as well. And I like having a bit extra for more drives, video cards etc.

Edit: one more thing, because I can't find a very good student price for win7 in canada as of yet (truth be told I haven't looked terribly hard) I was going to install XP on this machine until I could reformat with win7. Anyone see a problem with that using these parts? and/or have info about win7 student pricing in Canada that I do not? Thanks again!
