Needing a solution for my old desktops

I joked on Mastodon yesterday that my stack of vintage computer desktops proved too heavy to move when I needed to retrieve something that fell down behind them. I wasn’t kidding; this AT clone, SGI Indigo2, and XT clone have the combined weight of a collapsed star, give or take a few errant photons. This amounts to more than a mild inconvenience, for several reasons: I’ve lost more items behind this stack of wonderful, classic computing than I care to admit. Okay that’s not true, I would tell you, but I can’t, because I can’t move them to count. It’s made working on any one machine painful. I’d love to spend an idle Sunday afternoon getting a Hercules graphics card working on that AT, or seeing if I can coax a SCSI emulator to life using the SGI’s onboard controller, but it would involve moving all the machines above it away.
