Is this computer any good?

I would forget the 64 bit windows 7 unless its free because its just a rip off and i would use that money to invest in an I7 instead of a I5 and i wouldn't buy that case because i dont like it and instead i would buy the lian li Dark armor PC-K62 as i have had huge success with that case in the past and i still use it as my primary case at the moment due to its huge array of features. The caviar greens are realy slow and you will find your self complaining your computer is slow because of them even at 7200rmp they are slow compared to there counter parts the sea gate barracuda 7200rmp. But for a cheap computer just to play games on and if you aren't a huge computer nut then either of these are good for what you want.
