I'd love to get in touch with this company and ask them why they don't make any cases for the PS3. I'm sure a lot of people out there would love custom PS3 cases. They could make a good amount of money as they would be the only company to produce custom cases.
XCM if you are listening PLEASE make custom PS3 cases!
I'm sure alternate cases will be made for the slim PS3, because they would be cheaper and more simple to make.
