Well in terms of tha lcd again, I'm thinking about looking into some of the ones they
have at dexis.  They have piles of lcd's form laptops, the problem is the connector
(the aren't labeled and consist of a few pins, so it might take some tinkering).  But
then again if I can get it for around $5-10.....

I've changed my mind and am actually thinking of using a regular 4 gig laptop drive
for everything (root filesystem and mp3s).  I just need to make a cable that will go
from the drive to the power and the bus.  I also would like to find out what kind of
drive they are using for empeg (www.empeg.com) because they claim it can run at 100G.

All suggestions are welcomed.  But as I said before, this is all in the planning stage
still and probably won't happen until we get some free time.
