If you own a server post what it is and what it's specs are.
I have two servers, the first one is dedicated and the rest are on my daily use PC.
1. Web Server/IRC server/Mumble server
900 MHz ARMv7 processor
1 GB SDRAM
... and if you haven't guessed yet, that is a Raspberry Pi.
2. Minecraft server
Intel Core i5-4440 3.1 GHz processor
8 GB DDR3 1600 RAM
Nvidia GeForce GTX 750 Ti SC
... and I play on it at the same time it is serving!
