Suggestions

Well im thinking about buying a new computer but im low on funds. I've checked local stores (Best buy, Fry's, office depot, etc etc) and I havent seen anything that's under 900$ thats wroth buying. I'm looking for something that's long lasting and with at least 700GB of HD space.

A gaming computer simply put.

Build it yourself. Newegg is your friend.

Some links I found. I can't confirm if they would be very useful to you but they seemed pretty good by me(not that thats saying much...)

Built you an AMD based box on Newegg.



Under $900 and will run pretty much anything.
Oops forgot to mention the stock AMD cooler is rather noisy when it's under load you might want to consider a third party cooler if you have a bit of extra money.
My suggestions would be the True 120 with or the Noctua NH-U12P.
Use NH-U12P fans for the True 120 since it doesn't come with them and the NH-U12P should already come with a set.

You could make a pretty decent gaming PC by building it yourself.
