I will be able to advise on the PC side of things. Their are a few of us oldies out here(more than your list of 4) that have been through the trial and error phases, we will be able to let you know some history and guide you though what works.
but first off congratulations!!! and your off to a great start! Stay active with the community and seek guidance as you have, theirs a lot of help out here, just gotta ask.
I’m willing to continue as TF2 CL if the community would like, however i would rather someone on campus take first snag.
