We're currently using Satellite 5.0.2 on a fairly meaty Dell server (8GB ram, 
800GB raid-5 disk, 4 cpu).
To my mind this server is massivly over-spec'd for the job its doing, and 
spends most of its time idle.

/var/satellite is taking up 80GB (we have RHEL4 AS and ES 32bit, RHEL5 32bit 
and RHEL5 64bit)
/rhnsat (the database) is only 6.5GB, although we don't have that many servers 

A quick check on the Dell website reveals the Precision M6400 Mobile 
Workstation, which take upto 16GB ram, a Quad-core cpu and upto two 500GB 
This type of laptop would be perfect for a mobile satellite IMHO, although 
it'll probably be more expensive than a server for long-term use.
