Im starting to get the SFF bug.... I have been looking at them but cant make up my mind. I have built many systems but dont really know what to expect out of a SFF. I would like to keep the price aroud 500 to 600 dollars if i could. Also not that i have to use it but i do have a xp2600 laying around and 512 of pc 2100 and 2 40 gigs.....
