Several Different Questions

[Skv012a]

Hi guys, decided to join to get some professional answers to some of my technical questions. Everything will be about Slim, but if the concept doesn't change, answers about fat are welcome.

First of all, is it possible to swap UMD for an additional mem card slot? Have anyone attempted any other method of adding more slots?

How hard is it to make Chotto internal? What would I need/need to do?

Trigger LEDs- whats the best method for a circuit breaker? Can I wire them to a separate power sources tucked away in the UMD drive area and what would the basic setup looks like?

Many thanks for your time.
