Hah, actually I'm thinking ahead to this LT-alike I want to make. I'm gonna take it easy on the money this month, and then when I get my bonus next month, I'm gonna buy a whole bunch of furniture, take a week off and get the parts for the LT.
Basically, for the screen, I plan to make a PCE mould out of clay, then make a reverse out of plaster of paris, then vacuum mould the actual case, and use the now halved (baked) clay mould to impress the detail from the PC Engine top into it.
And then just to ice the cake, I'd like the logo.
Need to wait until I have all the stuff so I can work out the dimensions of everything, but I think it will work pretty well.
