I've been in this hobby for quite a few years now and still never came across the case of my first PC in 1993. It was a 486DX33 in a tower case. It was a rather spaceous beige tower with 3 5.25" and 2 3.5" bays. The distinguishing feature was that it had a door on the front that when closed completely hid away all drive bays. It did not have a segment display as far as I can remember, but I remember that it had a Turbo button. I can not recall for certain whether the buttons were behind the door or not, but if memory serves me right they were not.

I've don some image searches on Google to no avail, so if you ever owned such a case or have photos of it and can point me towards what it may have been I'll be grateful..
