We have 17 seats in my garage all with gigabit internet, power, tables and chairs. We have a projector and screen setup as well as the ability to record the play via twitch.tv. We also have 4 spare computers that live in the LAN room just for gaming to loan out. We can fit another 8 people in the living room too.
I've been hosting normal LAN parties here for a couple years now and after learning about Artemis I jumped on board HARD being the big Trekkie I am.
We're looking to get two or three crews together for some harder game play scenarios, we can have a couple crews in the garage and one in the living room even.
Click on "events" for our next dates. If we get enough Artemis players We'll be hosting dedicated Artemis nights.

You can see the "main screen" is projected on a screen mounted to the garage door.
