My personal jury is still out when it comes to computers with built-in touchscreens. On laptops, sure, go for it. On desktops, eh, I don’t know. Take the Shuttle D10, for instance. It’s got a 7-inch LCD screen built into it. Okay, I guess, but the screen’s only got an 800×480 resolution according to Akihabara. You’re gonna need to hook a monitor up to it no matter what.
I could see this kind of thing being useful for, say, a car PC project or maybe, just …

Like a long time ago that there were boxed PC, a CPU fan in such a large cube, such as toys, was also the kind of large-display interface standard. From the picture, the use of a low-voltage AC power, a reader, along with PS / 2 and USB interface.
