The only reason for this post was because I used the words Crash Box in A build thread and got hit with PMs asking what the heck it was. It's just one of those things you either do or don't do. If I have the room for one then I do, if not I don't worry about it and do things differently.
Found out Tower still sells them and they make A good one for little money.
This wasn't any debate. If you like the idea go for it, if not forget it. This is what one looks like.
Nuff Said.
