Maybe come back when you have an A500 & have tried cramming in multiple upgrades inside the case. A megachip and 1.8mb trapdoor expansion with a gary tower of death takes up a lot of the room.
I own an A500 plus, plenty of room inside so not sure where you're coming from. I've had various combinations of hardware inside/outside.
I've had an ide68k/ Tom's 8MB with a CFCard/68010 - This was great, nice and tidy, good for WHDLoad and the CF Card was mounted so you could access it without opening the case. This was the best setup, only thing missing was an 68030.
Currently I'm using an A590 (as I sold some 500 gear to fund my 1200) and find it takes up too much space on the desk and I'm missing my ide68k :-(
