Anyone know how to remove the case from a HD 20?

[Xyzzy_Magic]

Hello, everyone... I was hoping to use the newer immersion-with-Oxy alternative to retr0bright to de-yellow a Macintosh Hard Disk 20 (model M0135) case -- but I can't figure out how to take it apart, since removing the screw didn't make any difference. A half-hour of web-searching didn't turn up any directions, so could someone here possibly please tell me?

Thank you!

I would guess that there are plastic clips holding things together. Carefully try to pry it apart, also look for hidden screws under rubber feet and stickers.
