from what i've heard, no. However, there is good news - a Zalman 7700-Cu or 7700-AlCu will fit just fine, they work well and are really quiet. I'm thinking of grabbing one here pretty soon. And you could, of course, get an XP-90, although it'll be a bit louder with the smaller fan. Oh, and yeah, you'll want to be upgrading your memory pretty soon. My game load times were just unbearable with 512MB ram, even with DDR400. HL2 is particularly awful at this - I couldn't even stand to play the game with 512MB, i spent more time loading levels than actually playing, lol.
