Update: Finished the whole project! Clickly for pictures and a video! I'm looking into the viability of a guitar PC mod. Looks like it's been done before. This is actually good because this is my full case mod - it's reassuring that the concept is solid. The PC itself is intended as a backup/file server/iTunes server so a powerful setup is not needed. The main aims of such an project are: to run the PC 24/7 to still function as a guitar to be built as cheaply as possible Initial thoughts involve mounting an mini ITX system inside an acoustic guitar: Atom CPU on mini ITX mobo 2GB RAM 250GB 2.5" laptop (SATA) HDD some kind of PSU some kind of lighting slimline DVD RW (SATA) (?) Here are some initial diagrams I messed about with on Sketchup: (thanks to jezmck, models were excellent) Some thoughts: (1) Can I install Windows through a Flash USB drive? (Linux is no problem). If so, the DVD drive is not needed. (2) I'm thinking of mounting everything on 2 sheets of MDF or similar material (shown by the orange blocks); first one as a base for everything and second between the DVD drive and the motherboard. Velcro anyone? (3) There are two different cuts I can make to insert the MDF base (see pic). Cut 1 involves taking the whole back off and gluing the MDF onto the board. This needs a method of reattaching the back of the guitar. Cut 2 just removes the back panel, but gluing the MDF board onto the guitar will be a pain. Any suggestions? (4) PSU: Currently unsure what PSU to use. Was thinking of a 1U 250W, but can I get away with a smaller picoPSU? Will it have long enough cables? (5) Cooling: No addition cooling fans. Am I being optimistic? Should I include at least a 80mm somewhere? Any thoughts, ideas, suggestions welcome!
