RetroBSD is a port of BSD 2.1 for pic micro controllers, so a lot of the work is done for me! I'll be writing drivers for the lcd and key pad. I'm going to be making the keypad from scratch at this point, but performance wise it's actually pretty damned fast!
While the RAM is lacking, it should be enough :) the case will likely be vacuum moulded, I've experience doing that when I use to make portable consoles from hacked SoC's, but the prototype will be 3D printed for sure.
Does RetroBSD really work with only 32K of RAM? Their frontpage just mentions: "RetroBSD needs only 128 kbytes of RAM to be up and running user applications."
It's only for prototyping to be honest, I'm likely to end up wiring up my own PCB with the chips myself, to give me more flexibility in shape and speed, but for now this will do to get it started!

This is the board I ordered: http://www.seeedstudio.com/depot/fubarino-sd-p-1265.html
PIC32MX440F256H - 256K Flash, 32K RAM @ 80MHz 32-bit MIPS core

Oops, I linked the wrong board!

Little bit better ;)
