M had seen a server cabinet with some auxillary, most importantly a UPS, for sale. The price was 3000 SEK, which made it an acceptable extra cost to drive to Nyköping to pick it up.
We set off at half past five, and reached Stockholm traffic at about ten, so we probably missed their lunch hour. I wouldn't have guessed. Anyway, we emerge from it unharmed, and managed to find our way to a nice little former vicarage, where the UPS was waiting for us, along with the rest. The seller himself wasn't there, but his brother helped us load everything into the car, and his mother offered us some lemonade (delicious).
We have a large car, but to fit the cabinet into it we had to move the seats forward as far as possible. Now imagine us crouching over the wheel, with this giant metal box behind us. We looked hilarious (we have pictures). Then we drove back home, stopping only at Max in Bollnäs for a quick meal.
Now it's in our basement, and likely to remain there. We removed everything in it, and carried it inside between us, then we had to cause some damage to the ceiling (no, nothing serious) raising it upright. The UPS will do duty as UPS, and the server cabinet -- I'm sure we can use it to keep servers in, or something.
 Note for non-Swedish people: Max is a hamburger chain. Exactly like McDonalds, except that it's no different at all.
