This website is running on a small form factor Lenovo desktop PC with the following specs:

CPU: Intel i3-4130 @ 3.40GHz
Memory: 8GB
Hard Drive: 320GB
OS: Slackware 15
Network Speed: 100Mbps/10Mbps (up/down)

I got this computer for free from my local ewaste depot and it has been running fine since. I would like to replace it with a lowered powered PC at some point.
