It's not much lower, but I've got a Compaq DL380 with a single 733MHz P3
cpu and 512Mb memory.  I got lucky with  the disks - four 18Gb disks with
hardware RAID presenting them as one mirrored 36Gb disk.  Right now, the
bbgen page shows:

   bbgen for Hobbit version 4.2.0

   Statistics:
    Hosts               :   903
    Status messages     :  3574
    Purple messages     :     0
    Pages               :    40


There are only 895 unique hosts, as some a listed several times.  Roughly
3000 of the status messages are generated on the server itself, because it
is almost exclusively doing web page monitoring using custom scripts.  That
would be why the server's own cpu load graph shows a 5.7 average...  :)

It is running RedHat 7.2, and has been down for maintenance about 4 times in
7 years - once to be installed in the rack (after running for a year in my
cube), once when its power supply died, once when the building UPS was down
for maintenance, and once when I was screwing around with kernel modules.
