I just got a couple of Alpha's from 2Cool.
I havent gotten around to putting them in yet... but they damn sure look impressive enough! I like doing business with 2Cool because he is very helpfull.. he even helped me with some heatsinks I didnt buy from him (before I knew about his site) I plan on ordering a couple more soon for my kids machines.. and bump up the FSB just a tad.
He also has good directions on his site for assembly. If you plan on overclocking I would suggest an Alpha.
Forget AMD and Intel..
Cyrix is king!
Pictures don't really do the Alpha justice. When I got mine, I was struck by how large and heavy it is. It really makes the standard heatsink and fan look tiny. You won't be disapointed with this heatsink!
