At the moment i have two empegs

There is my noraml empeg a Mk2a and my back up which is a Mk2

What i would like to do is put the mk2 into a dock which i have.

Ideally this emeg would have all my stuff stored in it as in Mp3s Now since it ain't going anywhere there is no need for it to be portable.

So instead of going down the slightly expensive route of getting two huge 2.5 drives could i get one 3.5 and install that in the dock and get a external power supply for it and plug that into the empeg.

I know it means that empeg is tied into the dock unless i take the top off dock and pull cable off the motherboard.

Is there any snags anyone can see or shall i splash out on a central and upgraded it.
