Hey leclaude,
I have a pretty decent gaming laptop I can bring with me to the event if you would like to use it. It has 8 GB of RAM, 1 GB vid card, an 128 GB SSD and an i5 proc. I recently formatted it and can load most if not all of the LAN games on it in advance. There are also various tweaks to the config that I personally utilize for CS:GO to improve performance, so I can include that as well. If you feel more comfortable using your own computer, I completely understand, but wanted to throw it out there 🙂
