For those interested, here is some specs on what’s running the site:
1.6GHz Dual Core Atom Processor
2GB of RAM
Internal Wireless Card, 10/100 Ethernet
XBMC Live (Ubuntu-based, boots in ~30s)
XMBC, Mumble, Minecraft Server (more on this below), Deluge, Apache, MySQL
The Minecraft server runs Craftbukkit with the following plugins:
AdminCmd, ChatterCraft, MagicCarpet, MapMarkers, Nanobot, Runecraft, WorldEdit
The Minecraft world is backed up every 30 minutes. Overviewer is installed at tylerphawkins.com/minecraftmap/ and it updates nightly.
There’s other stuff running on the server and special configurations for different things, but most of it was made only for me.
I now run the site on an EC2 instance. This machine now is media-center only.
