If you’re really into miniatures, and want your PS3 to double as a board for your figure-based strategy game (I know Warhammer 40,000: Vegas is coming out soon), this sort of thing is plainly for you. A lot of work has gone into this completely impractical conversion, which was made for an Ubisoft promotion.
I’m more a fan of modding your case into a something, well, awesome, instead of a (albeit sweet) diorama.
