Yeah, i was half-kidding about that, anyways, it's going to be pretty good, i mean REALLY good, it's going to run any game, and will be compatible with the video card, etc.

Sorry, it's not the first time I take everything a little bit too literaly XD

Good then for your PC, is it pre-build or will you (or you father) buy parts and make it yourself?
I recommend the later, you get better (A LOT better) quality components like motherboard and power supply and you can updrage later without any problem.
(and you can overclock! I love overclocking...)

I will build by parts, and i don't like overclocking, your components will most likely melt.

Come on, don't repeat the old stuff "you heard somewhere"! That's how we end up with people believing that "we only use 10% of our brain", or that "the sky is blue because it's the reflexion of water" =_=.

Overclocking does not kill your components as long as you know what you're doing.
You can get like 20% more performance thanks to overclocking and your parts will maybe last much longer than someone else's because you took care of them and cooled them the right way.

DON'T, EVER, believe preconceived ideas. Don't believe blindly what others tell you because they say that they know. Search for proof. Build your opinion. That's the way I live and so far it only benefited me.

What i mean is, i fear i will end up doing the wrong thing and making my components melt, besides, i can have only one fan for the video card, the standard one, i want to consume energy as less as possible.

Lol I know what you mean, I didn't start overclocking right away, I feared for my components as well at the begining.
Correct me if I'm wrong, but your case will only have one fan and it's the video card fan?
That won't do, overheating will probably kill your PC in summer! Don't worry about consumption, fans consumes next to nothing.

Nah, the summer here in Brazil is very cool, it rains more than ever and the temperature goes down, maybe that helps?

Anyways, if necessary, guess i can do something.
