This sounds like a really worthwhile mod

Denise only has a 20 or 30Gb drive and wanted an upgrade anyhow.

It sounds like it's viable enough that I can go out and buy an 8Gb CF (£50), an adapter (£15) and a 120Gb laptop drive (£47), put it together, (find the PUIS pin if needed) and have a fast booting Empeg with 128Gb for a little over £100 - cool.

This would also stay cooler playing music that's on the CF?
