========================
From: "Glenn Meadows" <gmeadow@comcast.net>

Well, I think the Mini can have up to 2gig installed (it's not easy to upgrade
yourself, but can be done).

As to HD, it uses Laptop HD's, so 200 is beyond it's range.  BUT no reason you
can't put an external USB or Firewire drive(s) on it.  I believe it's got 4
USB2 ports, and a Firewire as well.
