That board cant be trimmed to any significant degree

The Dragon chip is on the far end of the board under the disc drive, and even if it wasn't, the DSP and BIOS are.

This version was the last one before they realized how small they could make the motherboard, which gave rise to the 7900X, you'll note how little space is taken up even despite the use of the old DSP

Yes you can absolutely make it portable. I was gonna use a 70011 before I switched back to the 79001. My plan for it was (and still is) to use an 8 inch 1024x768 screen and do it like an oversized PSP, but you could also go the other way, use a 5 inch screen and make it like an oversized gameboy, thoughts?

I don't think there is any the most you can trim is the ground plane im pretty sure and maybe up to some of the ports if you really wanted it to be small

just so many i am so cool
There is no all encompacing guide on how to build a portable. You need to decide how you want to wire up sound, video, batteries, a controller, everything else mostly on your own. If you don't have any experience with soldering or electronics, do lots of research! Practice!

A good list of the parts we like to use can be found here.

Good luck!
