Well, first of all thanks to @Mrcento - got the spare case from him at Hopetoun last year. That's what you see in the pic above
Also cheers to @Ryanfaescotland. Headed over to his this afternoon and we sat and changed over the inner workings of the old dreamcast into the new shell. Powers up and plays fine
Gotta do the controller next and eventually replace the internal batter and might use that as an excuse to change the LED.
I really can't believe what a good finish this has got on just a coat of paint and a bit of sanding, looks great. What an improvement over the original yellowing plastic.
