I had a spare honda tape din sized unit from my prelude. I took it apart and wanted to use it for my project somehow. After checking out the mesurements for a few Mini-ITX boards and the unit, it would be possible to mount the board inside the unit, with exception of a
power supply. It would be din sized and if you could use a add on OEM Cd player, you could even mount a slim line cd-rom, and get a realistic OEM Look.I don't currently have a board, but the dimmensions I found were 17cmX17Cm, about 6.7in. This unit is about 7.8inX6.8in roughly.I'll try and upload some pictures so everyone can see what I am talking about. These units are pretty cheep off of e-bay, or a local salvage yard.
A Nano Itx board would work even better.
