Note 1: When disassembling anything, it's usually a good idea to take photographs, so that you know where everything goes when you're trying to put it back together again.
Note 2: The first note is less effective when the item that you are trying to reassemble was forcibly disassembled by the postal service and pieces of it were rattling around inside the case.

Not so long ago, I got an SGI 1600SW because I thought it would let me use the SGI Octane. Silly me. However, it does give me a chance to try designing some actual hardware, in the form of a converter from dvi/vga/etc to OpenLDI.

However, during transit, part of the plastic adjustment mechanism broke off and I decided to reassemble it. Easier said than done, considering that pieces were everywhere. If only I'd taken some pictures of disassembly, then I could have made an attempt to reassemble things and stand a chance of putting them back in the right place.
