Sorry, forgot to put my components, I am getting the Core i5 3570k, the MSI Z77 (possibly the gaming version), the XFX 850w PSU, and the NZXT Gaurdian case. I have left out graphics cards as i will be running on integrated graphics for a while, but my question is: is there any problem with these parts, and also is there anything else i will need? i have RAM, hdd and optical drive already that i know is compatible.
