Bunsen-- Yes, it does look similar. Perhaps it is designed for such use, but the previous owner instead took out the upgrade's original CPU (an '030?) and used the IIfx's CPU instead.

Note, however, that it doesn't have any provision for an FPU.

It came with a fan, similar to the one in your picture, but it was badly installed (a big mess of thermal compound and hot melt glue that broke loose), so I removed it (it shouldn't need one unless it is clocked really high, I don't think)

Kind of a mysterious little piece of history here!

Once I get a video card, I'll try it out.
