Utterly Mad

I'm considering upgrading my internet speed, and I was wondering who'd be up for a Minecraft Server? I'm probably gonna build a cheap little computer to host it on since the hardware requirements are quite low, but it probably wouldn't be a 24/7 server, could likely comfortably have 100+ people on the server though.
I'm not entirely sure when I'll get around to doing it but if there's interest I'll give it a go.
