The Yogscast Jingle Jam! They do an annual month long Livestream where they play games and raise money for a variety of charities. Donations of 35 pounds or more also get a whole bevy of game keys as part of the collection that can be redeemed on steam. You can see the list of games or donate at jinglejam.tiltify.com
I use mergerfs to pool a bunch of varying sized drives and then run snapraid on the whole pool to protect it. Then, I've got Kopia backups running and backup up to a remote repository. This solution has been flexible and I've already been able to recover from 2 drive failures very quickly and easily.
