No way in hell would I ever frankenmolest a 1200 into a tower case for any reason. Especially for the sole reason of introducing PeeCee crap to it, never mind all the headaches you'll encounter along the way. RTG or otherwise. Much better idea to violate the already ugly and sterile case of an A4000 for that purpose. Or better yet... get a MorphOS machine if you want to play around with a fancy hi-res Workbench that you'll end up bored with in a few minutes. :lol:
