The server is the inch-tall black box near the top of the computer stack. It is a specially-built Cobalt RaQ system with 256MB memory, 16GB disk and a MIPS 400Mhz processor, running RedHat Linux 5.2.
The two beige boxes below it house the Avatar Archive, an anthropomorphic image site. Yes, the sticker on the front of it is from an airline dog crate and says "Live Animals".
The box on the very top (the small black one) is an Ascend DSLPipe router, which provides a 960K connection for FurryMuck to the internet.
