As a comment, this is what I'm moving to as a FIRST STAGE:

* Two identical cheap boxes (~$500 each) running RedHat Linux, acting as
routers and firewalls (ipchains). These provide redundant routing to the
outside to avoid single-point-of-failure. Identical configs.

* Two identical nice boxes (~$1,200 each) running RedHat Linux, acting
as my primary servers. These run the following services:

           Box 1           Box 2
          =======         =======

DNS             Primary        Secondary
HTTP            Primary        Secondary
FTP             Primary        Secondary
SMTP           Secondary        Primary
POP3           Secondary        Primary
IMAP           Secondary        Primary
Database       Secondary        Primary

* My second stage will be to cluster Box 1 and Box 2 together for high
availability, and to create a second cluster of Box 3 and Box 4. Then
the two clusters will take on these roles.

* Of course I'll buy nicer hardware as I can afford it. Even so, I've
proudly got 99.9901% uptime on my server so far.
