Rev. A iMac G3 in mac IIci case and powered by ATX. - 03/03/07 06:11 AM

OK so I have an old iMac Rev a motherboard and 256 mb of ram. the system was a 233 but I got a 333 chip for it. I will need info on ATX moding and overclocking (to 400 MHz).

OK thanks

I don't know anything about putting the iMac's mobo in an
ATX case, but something about the overclocking. Be sure to
check http://www.bekkoame.ne.jp/~t-imai/imace1.html , it's
the authority on overclocking the G3 in my opinion.
You have to be careful, though, the PPC750 base chip just won't
put out more than 450Mhz, and I only got my REV. D to 400Mhz.
Overclock with care!

It's very plain and simple. http://www.xlr8yourmac.com/systems/imac_in_PowerCenter_case/iMac_in_powercenter_case.html#storytop

You don't need the special setup for the power, just connect a switch to a ground and the green wire.

I've had a headless iMac for about 2 years now and hasn't died on me yet.
