Whew. Upgrading computer hardware is always more tiring than I expect. I think it's to do with kneeling on the floor while needing both hands to do things - you have to support your body with most of your other muscles, and not only that but you typically have to hold yourself absolutely still because your hands are doing something delicate inside the guts of the machine.

Still, all done now, the machine is mostly working, and much whizzier than it was yesterday. Though doing this just after having a shower seems to have been a bad plan, because now I'll need another one!

And to think I declined a trip to the air show today because I didn't want to tire myself out. Oops.
