How to store (short-term) old computers?

Hello, all, I am in the process of building a new home. However, the process isn't simple. We can't afford two mortgage payments at once. So, we are building a nice shop building on our property first. We'll then move a bunch of our stuff into the shop building, and live in a motor home on the property once our current house sells. Then, we'll begin building the house. I'm looking for advice on how to properly prepare a couple of vintage computers and periperals for storage in the shop. The shop will be insulated and sheetrocked. I plan on having a propane heater, and a 1-ton air conditioner to keep the temperature reasonably well controlled during the winter and summer. The floor is a concrete slab, and won't be covered initially. When the equipment first moves in, the insulation and sheetrock, as well as heat & AC might not be in yet. It all depends on the timing of the sale of our current house. Given that there might not be good temperature control (temps could get pretty cold in winter, and hot in summer) is there special prep. that should be done to assure safe storage? I have a PDP8/e system with two RK05 drives, a dual RX01 floppy drive system, and a paper tape reader/punch. I also have a PDP11/34A, with two RL02 drives, three RK05 drives, and an RX02 dual floppy drive system. Both machines are mounted in original DEC racks. My guess is that the machines will have to remain in stasis for a period of about 12 months or so before I'll be in a position to be able to revive them. Any recommendations as to how I should prepare these machines for moving, then storage? Moving them in the rack could be a bit of a problem. Would it be better to unrack the devices for moving, then put them back in the racks for storage? There'll probably be bugs that will be able to get into the equipment which it is in storage? Should I wrap the racks up in some kind of wrap to prevent bug-type critters from getting inside? If so, do I have to be concerned about condensation or 'stale air' causing any problems? Perhaps a couple of good-sized dessicant packs should be put in there if I seal them up? I'd appreciate hearing from anyone who's had good luck with short-term storage of old computers.
