Cover Galaxy has it in their forums.
Thanks for the reply. I actually saw that cover on CoverGalaxy, before posting my request here, but it's not really suitable for printing. It's low resolution with too many compression artifacts.
I did a search on Google and I found all the parts to build the cover.
I found a high-rez version of the front cover and was able to build part of the spine, but I haven't been able to find a high-rez scan of the back cover or a good PS3 template.
