The boys at TechIMO have two things for us, they take a look at the hardware
scene in 2004,
then they post a Linux Terminal Server Project guide.
Basically K12LTSP allows you to take older machines 500mhz and less and
turn them into usable thin clients for a faster server. In other words, take
an old, slow, antique machine and give it new life instead of throwing it into
the trash bin.
