Assuming this server will be dedicated to PostgreSQL only, the needs
outlined above are modest.
As was pointed out in other posts, a simple sub-ghz machine with 512mb
of ram is more than enough, but I'd slap on a gig only because RAM is
cheaper now. If the database on this server is crucial, I'd look at
setting up a UPS, RAID (at this level, even software-based RAID will do
fine, RAID 5 preferably) and investing in a backup/replicator solution.
