The QL sold most when it was marketed as a bundle. With software, printer and a keen price. One of the desirable and attractive features of the system was its distinctive black box styling. This at a time when all home computers had their own distinctive design.
The last 20 years of hardware development for the QL has seen it boxed up in PC style tower cases to look like a "proper computer". This was probably a mistake. I recently came across this web site http://www.mini-itx.com/store/, marketing nano itx boards and lo and behold several enterprising individuals have boxed these up in old computer cases and installed emulators. The QL has several excellent emulators that could run under windows on one of these boards. This is the opporunity for back to future QL hardware! Or back to black as someone else said.
I have no commercial interest in the miniitx store and where marked images are their copyright.
