had a MacPlus, wanted to add an Emachines BigPicture (17 inch screen).
I put in a Mac SE logicboard, a HD drive, and PC power supply, and a 200 megabyte harddisk. Attached a 17 inch Big Picture. The Mac hid partly behind the big screen , just poking out enough to provide acces to the floppy slot. Totally awesome combo!
Gaming was great too, since the slowly decaying phosphor made for smooth graphics.
