Revision 2: October 2000
The hardware started out with two 4U rack mount cases which I moved existing hardware into.
Since everything in the rack was intended to be black, I had to locate black floppy and DVD drives - this proved surprisingly hard. Most vendors don't mention color (which means its white/ivory/beige). It was the home theatre PC industry that came to the rescue.
Each server has its own APC 1U 450VA UPS. The UPS is wired to the server so that it can signal a power failure and allow logging of power events and elegant shutdown when the batteries run low.
The 3Com DSL modem and Terayon cable modem, along with two LinkSys routers (one for each modem) were placed on top of the rack mount computers and provided both routing and networking connectivity (four RJ45s in each router) for the network. There was no attempt made to load balance or fail over between the two Internet connections.
