Pretty good game pc

[AncientBro]

Hey,

I was wondering if someone could say to me if this is a good game pc:

I, myself, did quite a bit research and i also have advanced knowledge of good gaming pc's and systems.
The problem here is that I never actually bought a computer myself (I got my current one from my dad which is crap).
Although I did quite some research, I want to know if this is really a good purchase or not.

Ps. There is no Windows 7 or 8 installed on it so if you know a cheap way to buy Windows 7, please do tell me. Also, I wanna know if the cooler of this computer is good enough.

Thanks already

AncientBro

Its a good PC but you can probably build one for cheaper

Well, the problem with building one is that I don't know which parts fits on which other part. Maybe you can give a suggestion or a list of parts that fit together and are similair to this computer for a lower price.
