Just out of curiosity, Galagafan, if you like those cabinet models, have you considered just running 3DArcade? It's easy to be scared away by the "high learning curve" that so many people associate with it, but you may or may not be aware that there are ready-made 3DArcade DVDs... they are up to DVD ver. 3 now... which have been designed and released by generous 3DArcade forum members, which aim to do away with most of that learning curve. And you will find the forum members over there to be very responsive to any questions you may have.
Just a thought
