Quick heads up, the mainsite isn't affiliated with the Containment Breach game, and most of the writers here have actually never played the game. If you'd like to talk mods/gameplay/videos, the CB forums are the place to go!
If you're thinking about becoming a site writer, you should first create a sandbox page to keep your in-progress works, references, or ideas in development at. When you've got a draft ready to be read, bring it to the IRC chat and/or the drafts forums for reviews so you can make the necessary edits before a mainsite post.
I have a friend who likes to tinker with PCs. One time he refurbished an old hard drive into a Minecraft server for our tech group in high school. Any particular models you like to work with?
I hope you enjoy your time here, and welcome to the site!
