That nice miggy is in desperate need of a case! I remember doing the same thing with a a500, cables everywhere cd drives on top.... what a mess. The expansion I had was a Viper 520CD. Gave the 500 8mb of Ram, 4 IDE, 020 33mhz, v3.0 roms... its one of the neatest expansions for the 500. Minor problem, if you don't towerise it you end up with a spag ball problem as Malboro has found.
