Here are the parts i was thinking of getting for my build, I just want to know if everything is compatible and what size PSU i should get. I want a PSU that will support all of this and also allow me to upgrade to a better graphics card in the future and possibly more/better RAM. Also what other factors should go into picking out my PSU other than wattage as far as brand/anything else?
Visiontek isn't a respected RAM maker. Switch that RAM out for a Crucial or Kingston set of RAM instead. CT2KIT51264BA1339 is about the most ideal set of RAM there is and you are probably fine with 8 GB anyway.
It is harder to use that much than you think.
The 2600k is probably a bit overkill for whatever you are doing. The 2500k is very nearly as good and costs much less usually.
Video card - Too small for most serious graphics using programs. I don't know what you intend to do with this computer, but I would advise you set a minimum of a HD 6850 as your graphics card if you intend to do anything remotely graphics intensive.
Windows 7 - I would get a student version of Professional for about $65 if you have access to a student email. Either that or a retail upgrade (non-OEM) version of Professional for about $100 if you have a legal copy of windows right now that you don't mind agreeing not to use.
Both those methods get you a legal copy of Windows 7 for pretty cheap.
Case - There is no good reason to get a $250 case if you are going to have a $50 video card in it. The case should always cost less money than the video card in it as a rule of thumb.
You would be just fine with a nice HAF 912 or 922 instead of the beastly one you chose and it would save you $200 to put towards the other stuff.
If you intend to stick with a low end video card, you should get an XFX Pro 450w Core PSU. If you intend to upsize the video card then get the same maker/model but a 550w instead.
