The second Gateway case uses a standard ATX PSU. I have three of those
cases myself. Dunno about the first one, didn't even think of that.

How do you know that it's exactly the same case though? I think they
used the same bezel style and general internal configuration on cases
with multiple different PSU. I noted the smaller, square PSU opening
in the back

to look similar to those that use the proprietary PSU, perhaps like
these

This "appears" to be the rear of that case, if the ebay seller linked
to the correct Gateway specs, and it does "look" like it has the
proper screw holes, but not the full fan opening:

Now that I see that pic, it looks easier to install a standard PSU
than i had anticipated, but I still wonder about the airflow if the
fan exhaust from a standard PSU (with fan in rear instead of
underneath), and if the PSU's AC-receptacle isn't flush with the
exterior plane of the PSU casing, but rather has a "lip" external to
the casing (as it often does on many standard PSU), if that would
interfere with the chassis' smaller square cutout.
