Are there any restrictions on the purchase of individual computer parts, or restrictions on assembling those parts for a fee? What about the import of those parts, or a whole high-end gaming PC from out of state, post sale? Would leaving the state explicitly to purchase a high powered gaming PC be illegal? A federal crime? This just feels nominal and designed to send a message, but I genuinely don't understand that message. Gaming is bad because it hurts the environment? That's not right... So many questions, and I'm suspecting there are fewer answers.
