I have never built anything before and need help. I'm mostly happy with what i picked, but i'm not really one for this and probably have missed something that doesn't work with everything else. About 750/800 is good, but of course, less is better for me.
Excellent Ram, good psus, hdd is ok but the op should make sure he updates the firmware, you could also get a 1 TB drive from newegg for $65 http://www.newegg.com/Product/Product.aspx?Item=N82E168... I'm pretty sure this is as fast as the seagate but I'm no hdd expert. I'd expect it to be though, as it is 7200 rpm and has 16mb of cache.
