We have several Dell Optiplex 320s where I work. Their PSU is a off size,
and slightly smaller than a normal ATX, so you can't replace it with a
normal unit if it goes bad. (Only 320W too) The motherboard may be BTX,
but it mounts upsidedown and backwards in the case compared to an ATX
board (not all that familiar with BTX format). Oh and while the clock
chip in it is capible of 400 FSB, anything above 200 FSB isn't allowed by
the BIOS, so don't think about upgrading from the E2140 chip that comes in
it.
