You don't need an IDE splitter, if you mean a buffed IDE interface, as you would use on an A1200. In fact the A1200 ones are not compatible and can damage the A4000s IDE port. All you need is a standard PC IDE ribbon cable with 3 connectors on it. One for the motherboard, and 2 connectors for the devices. The A4000s port is already buffered and supports 2 devices as standard.

If you add a CD drive you will need software like IDEFix to get it working.

Remember the 040 well be faster for workbench and applications, but it is the least compatible 68k CPU for games. You should also add the 040 library into workbench so it's additional features and supported.
