Personally i have three expanded A1200's on one single desk. One in a tower but the other two with peculiar home-made wooden boxes containing PSU and drives etc.
On a desk next to it, i have an A4000T and a A500+, with various expansions.
Between these, on top of them, on the floor and even on the walls there is cables, cables and more cables. And the occational harddrive or expansionboard. Plus some of the stuff i have bought and are trying to get to work, and the random soldering iron lying around here and there.
That is the way I like it
Anyway, that's nothing compared to the table in the cellar where my two BBC Micro's are placed. Now THAT is a mess
