A few clarifications, just to help you out, vesaker.
1.) Rawhead Rex is a Clive Barker character from his Books of Blood series. There has also been a film based on the short story and a comic (I think there was a comic, anyways...)
2.) Hellraiser Inferno is the flick you're referring to. I honestly never pieced two and two together to realise that the same actor who played Boon in Night Breed was the corrupt cop in that film!
3.) The name of the puzzle box is the Lament Configuration.
