Yep... just joined up last week. I have a 2.0aGhz P4 (o/c to 2.4), and AMD t-bird 1.2Ghz (o/c to 1.35) and a Celeron 300amhz (o/c to 450) working on it.
My t-bird is working 24/7 with little other usage of the cpu. My p4 is also working 24/7, but it is the one I use as my main, so I am taking cycles away from it more. My 300a celery is working when my dad has it on. Mostly from 4pm-10pm each day.
Soon I will have my new
AMD Athlon 2400 XP (G/A? Representing @ the AMD Reality Check Tour) working on it once I get a mobo and memory for it.
