There's a 7" touch screen available with a plastic case that contains
both the RPi and screen while giving access to the ethernet and USB
sockets. It will fit models 2, 3 and 4, but you may not want to put a
model 4 in it for cooling reasons.

This package needs only a PSU, keyboard and mouse to operate as a stand-
alone computer, though there is no room to add expansion cards or 'hats'
to the RPi.

Alternatively, there are cases that would hold just the RPi - add a PSU
and an ethernet connection to a PC and you have access to the RPi over an
SSH connection. If the PC is running Linux. nothing more is needed. If
its running Windows, you'll probably want to add PuTTY or a similar
package to your Windows box so you can run the RPi as a headless system
that you can login to from the PC and/or transfer files.

You can do the same with a WiFi dongle too.
