At present I'm using two MiniPCs and a RaspberryPi4 with each connected to a single 27" screen via a smart HDMI switch.
Keyboard and mouse are wireless and pretty low cost by Logitech, so the vowels, plus R and T soon wear off meaning one
or two replacements a year. To switch from one PC to another I just swap the dongle.
So my mice have the lifespan of the lettering on the keys before they also end up in the bin.
