Hi,

minimal heat and power would point to an old laptop. Putting it on edge
shouldn't be a problem because Harddisks are usually specified to work
flat or on edge. Display and keyboard might be an added value for the
installation.

P.S. The fixed fee for ISDN in Germany is a bit less than the fee for 2
analog lines which it replaces. My internet connection is a dialup line
using 1 B-channel at a cost of 1.9 Pf per minute (about 1 cent).
