In the
Technical Overview section of the
Dim2400 Manual It looks like it's a standard power connector.
You might find someone who has done this at
Dell forums.
According to opinions there here are some possible problems with changing the motherboard:
~ The front panel connector connects through a propietary ribbon cable, you'll have to rig some way to hook it up to the new motherboard.
~ The motherboard mounting to the tray may be different than standard
~You could re-use the processor, but you'd have to get a new heatsink. The Dell heatsink only fits into a Dell motherboard retaining clip (this I've read for other DIMs).
~ The OEM XP is tied to Dells motherboard BIOS so you'll have to ask
MicroSoft to validate it which they have done for some and not for others
It might be easier to just get a new case, but that still leaves the question of OS validity.
I only read a few threads and didn't see a post from anyone who had actually attempted it - you may find more certain answers if you search more thoroughly.
