Arch seems like it would probably be one of the best distros to pick for gaming because of Valve’s use and support of it for the Steam Deck. I can’t answer the specific question

Yes, you can legally vote from jail/prison, however many states, and local counties, will make this difficult. You lose voting rights for a felony (possibly just a subset). A misdemeanor does not impact your voting rights.

Without double checking, I’m guessing this guy was charged with a felony. Most of the January 6 charges were misdemeanors, not felonies. It really feels like your should lose your voting rights for at least 1 election cycle if you’re charged with some sort of election fraud or trying to over turn an election

That was my first thought as well, and I already own the Doctor Who set. I’d buy another TARDIS set. It’s retired now, so it’s a bit expensive now, https://www.lego.com/en-gb/product/doctor-who-21304
