don't blame you. i want that as well but i don't think that's possibal. had to buy a new pc as my work pc blow up. psu, cpu, ram and mobo gone in one momment. mind you i'm not complaining, means i can play the most up-to date games now.
But a proper blue psp would be fund to mess about with. totally mod the case's look. make a real oem black on blue, or red on blue. hmmmmm... once i get this blue case i might do that.
