It doesn't look like you've finished removing the case. It's hard to tell from a single photo but the top plastic case element is still clipped in. Keep taking parts off until there's room to lift or slide the mobo out.
I did not try to disassemble completely. Disassemble the case to install a hard drive in the computer.
To remove plastic computer case you need to unscrew only one screw. He is hidden under a small cover.

Pull the closing of the floppy disk drives.

Then take off the upper part of case.

Then the rear part of case.

Then it is possible to remove the side part of case of the enclosure and use a screwdriver to access to the motherboard.
