If you want a amiga gaming box, then i would personally go for an aga based machine with HD, some fast ram and maybe an accelrator. The a1200 and a4000 can run most classic ocs/ecs games when installing them using whdload. Not only will most games work perfectly, but you also dont need to swap disks and wait ages for the games to load and you will be able to play newer aga games which wont run on the a500 or a3000.
