just b/c everyone else is adding to this, I can't resist:

I have a BRAND NEW addtronics 7896A [of which SuperMicro SC-750A is an oem
release]. This is a server case, with removeable swing-open doors, removeable
face-place, and space for redundant power-supplies.

The face-plate fastens the doors closed, and there is a tubular-key lock on that
face-plate. That lock fastens the case. No wires attached, no keyboard disable.

I realize that this is a server case, not in the same league as a desktop and/or
tower, but the original post'er said that 486 case was a server case too.


I concur with a previous post-- just take that case to a locksmith; should cost
no more than $15 to pick that lock... & don't be surprised if it takes them no
more than 2sec ;D
