i5 3570K will be around $230 (because no games, cpu integrated graphic + z77 should do the work?)

so i think the motherboard should be around $140-$200Max, cause I'm not OC an I7. It's just an high performance Office PC so i guessed that they all works?...

MSI Z77A-GD65

ASRock Z77 EXTREME4 <--I‘m not sure if it is a good brand
http://ncix.com/products/?sku=70902
ANY HOW, I have no clue about the voltage regulator... and how it has to do with OC...

I have no clue of choosing a ram...the intel cpu page says "Memory Types: DDR3-1333/1600", so i suppose the max frequency supported is 1600Mhz? OR can the cpu support 1800 and higher when in OC?

Inaddition, please choose a cooling fan, power supply, case, and hdd (1TB)

Something along these lines would be more than capable. You don't really need a mobo, that gives you the added benefit of using TWO graphics cards, when you don't even plan on ONE.

Even if you're not planning to build, for few weeks, CPU deal, at Microcentre, is worth grabbing, if you have local branch. Will cost at least $45 more, elsewhere.

Your original motherboard has SLI / Crossfire support which would allow you to run two graphics cards simultaneously, since you don't plan on having a discrete graphics card - there is no real point to spending extra money for that capability

Malbluff's build looks pretty solid, I'd pick up an Antec Three Hundred Mid Tower instead of the NZXT chassis, but that is largely due to personal peference
