Heh, I\'m not planning on water cooling (too much of a hassle IMO). I\'m just gonna OC whatever I can with the stock fan. 3 GHz shouldn\'t be out of reach, but 2.8 GHz or whatever will also be just fine. I can always get another fan if need be (and I don\'t think it will).
As far as the harddrive goes - I need it soon. If the WD is out by then and around the same price then I\'ll of course consider it. But so far the Seagate is my choice and it\'ll do just fine. It\'s fast, stable, easy and reliable. Oh, and very quiet.
