That was my first thought, too. Huge chassis vs second monitor vs some space to park a laptop or actually scribble on paper. Too much other junk always cluttering my desk, lol, using two keyboards and two mice doesn't help.

But yes ... wall-mounting. Your solution is most excellent.

KVM hardware already switches to remote terminals, lol.

The keyboards are mapped to different layouts (English QWERTY, French AZERTY), I constantly need to swap them and I've found it's easier and faster and lazier to just slide a keyboard over than to toggle buttons and clicky settings. They're also both full of macros. Twice as many keyboard USB ports is sometimes handy. And my workstation is also my workbench, it shares space with some tools and problems, it's sometimes handy to have a second keyboard on the "other side" of things, it's sometimes handy to just stuff the keyboard into sliding undertray.

It all started years ago when I gamed with a Steelseries Merc Stealth keyboard, awesome beast for the kinds of gaming I did back then ... but utterly useless and frustrating to do any "real" typing or coding, so I ended up buying a second keyboard ... then a second mouse, one ambi and one right ... years passed, hardware changed, wants and needs evolved, but my main workstation setup still retains two keyboards and two mice and a big desk-covering sheet of material which basically serves as a "mouse pad".

A little large but a cool build!
