I am currently putting together three vintage computer builds. DOS/3.1, 98SE and XP

I don't have a lot of space so I'm trying to setup a sort of KVM thing for all three.
I'm planning to build a box that holds the monitor, keyboard, mouse and maybe the gamepad. There will be a gameport on it for joystick(s). This can be hung on a wall for storage.
The idea is that the computers will be on one side of the room and connect to a KVM switch then the cables (possibly with ethernet extenders) will go to another corner where I have a table.
When I want to use one of them I would open the peripheral box and plug it in.

These are the current peripherals that I'm considering for this.

LG 22M38D-B 21..5” 1920 x 1080
Dell QuietKey Keyboard SK-1000REW
Microsoft IntelliMouse Optical Mouse USB
Advanced Gravis Analog Pro Joystick (The one with grey buttons)
Logitech Wingman Extreme Digital 3D
Logitech Wingman RumblePad

I know that I will have to use adapters on these so they can connect to the different computer ports (ps/2 to din)

Any Thoughts on whether this can work, peripheral choices or suggestions on how to make this work better would be appreciated.
