Allison is spot on, I'm using aptiva semi-atx motherboard but fits
the case with i/o plate removed and running 233mmx. The
ps/1/aptiva/intellistations were basically the same motherboards,
just different packages and warrenty support levels. for example:
aptiva 2133-s16 and at least 2 models of intellistations used same
intel's LPX FX chipset type motherboards that used "EISA style
connector" for riser slot card.

Correct again, Between model 25 all the way to 40 are ISA ps/2.
The another ISA small box is model 33. Above that, all MCA. I find
ps/1 2011 or early 386sx in same box attactive for it's size. At
least thanks to this 2011 idea, you can now buy small boxes with
small footprint celeron/pentium/pii/piii, athlon/duron with
everything for a grand.
