I've done something similar.

I used an old radio case - speaker on the left, small door to access the 
knobs on the right.

The speaker I replaced with a small VGA LCD display.  Then I built an 
RC2014Zed and put it in under the door.  The door area made it easy to 
hide things, including a USB/Serial cable on the aux port so that I 
could transfer files easily.

Finally, I hooked up my own reset button and mounted it externally on 
the case.

The end result is something that looked more like a short Kaypro than a 
TRS-80 4P, but it works nice.
