Dom,
I only mentioned Directory Opus (v4.xx) because it is an essential tool. At least, I think so, and so do a lot of others. It can be used to simplify things like copying files. It is the equivalent to Windows Explorer, but much better.

Just thought of this... if that machine is a 1200 would you not be better off to get an IDE CDROM and just hook it up to the existing hard drive (IDE) cable? Of course, this assumes that there is only one drive on the interface.
