KennyR have you thought about a 35W Athlon XP-M? It'll drop right in any Socket A
motherboard, is cheap, and Nexus makes a 19 db Athlon/Socket A cooler that should keep it very quiet. 19 db is quieter than most "silent" branded PSUs...so it would practically be inaudible.
Im pretty sure I've seen 35W mobiles @ 1.8 GHz, while that's not the "bleeding edge"
it's still decent, especially compared to that Cyrix.;-) And they're very overclockable -
you could easily hit over 2.0 GHz speeds with that Nexus cooler and some good case
ventilation. (Even at 1.8 GHz, I imagine the performance is at least equal to the GX.)
