I just keep a cheap screen and a cheap keyboard near my servers. No need for a mouse. For my garage and basement servers, the KV stays in place always, and the MIL's condo, the KV goes away when not in use... and the keyboard got moved at some point, so I have to remember to bring it over when it needs adjusting.

Around me, most days I can stop at goodwill and get a monitor and keyboard for $30 or less.

The issue isn't cost in this case, it's the storage and effort of having to lug it out and put it back afterwards. Even if someone gave me an old screen and keyboard for free, I'm still not going to build that server PC. I've been looking into PiKVM as advised by another comment and they're pretty pricey at ~£200 but that's genuinely orders of magnitude more preferable. In another conversation on another platform, I was told about nexdock, which is more for docking phones but can be used as a dumb terminal, which is pretty enticing... though their website is pretty dubious, eg: the shop doesn't even tell me what version of the nexdock I'd be buying.
