I have a new Asus All in One ET2410 IUTS B034C 23.6 inch desktop. It comes partitioned into C and D drives With only 80 gigs in the C drive and 365 Gigs in the data D drive. This seems to limit what I can load onto it.

Is there a way to use my old Asus desktop which has 2 Hard Drives and connect to this All in One and use them as external data drives. Can my old tower connect with Usb's or HDMI's or some other way?
