I was thinking lengthwise, yes. Not sure how it'll work with the retention mechanism.
Using a couple of fans, I don't imagine it'll be over $5 (there's a swap meet this morning where I plan to get some goodies). Buying two new HSFs will cost me a minimum of $10 ea + shipping that I've found online. The previous post with the $18 idea would cost twice as much as that. This is just a dual p3-600 that I'm not even sure will work when I put a new vid card into it, so I don't want to drop too much money into it at this point when I'm trying to figure out what's wrong with it.
