Well...24 of them are tiny little ARM servers in the form of an HP Redstone tray. Single monitor windows (gaming) system on the left. Dual monitor CentOS machine where I do most of my work. Then there are two clusters--a three node AMD system with an HP Microserver acting as the head node, and a 24-node ARM-based cluster. Additionally, there's a small-atom based computer behind the little stack of SSDs that runs Linux and acts as my firewall and VPN.
What's it that you do?
Well that would explain a lot. Very nice setup!. Currently waiting for some extra money to get a server for home to manage backups and such :).
