Space, the final frontier.
I'm currently considering a major shop reorganisation. I've bought some 19" rails to start the process. (Actually, a big cleanup is in store first, but I need a goal..) I'm going to aim for a special mains supply in the form of isolation transformer and variac, all built into a 19" 6HE Baugruppenträger (DIN Eurocard frame). In addition, in anticipation of more 19" boat anchors, I'm going to reform the shelving to take all 19" slots; since I've got two [hp] 6200 series supplies, they're going in 2HE together, as soon as I have bought the rack mount kit (there is NOS available). Likewise, I've got some slightly newer half-width [hp] TE, and they'll live on shelves or rack mounted if I can find the kits. Long-term, I'd like to get a 19" frame for my 500 Series modules too.
This will not help much with shop place for storing less prioritised instruments, but it's a step in organisation direction. I'll try to get rid of the stack of storage bins on the floor in the workshop, and once that's done I can better use the secondary bench I've installed.
Then comes the rest of the garage...
