Desktop Tower Cases Where Can If Find "desktop" (not Tower) Computer Cases?

Where can if find "desktop" (not tower) computer cases? - desktop tower cases

All calls to the office towers. I need to be a group of desktop computers such as the "desktop" design, where you can create on the desktop of your monitor location, ideal for the situation.

Something like the old Dell GX110, which can be easily removed, would be ideal. Thank you.
