I honestly would contest the price for the ryzen because sure thats how much you pay for a new one but at the same time there are ryzens (am5 sadly) out there that have a lower power consumption, same or better performance at the same price. Another contention would be the hard drives. I would personally never use second hand storage, mostly because i am a paranoid fuck wit, but for me a used drive is at most worth half a new one as soon as someone puts their filthy data on it. But yeah the 4080 is still pretty expensive.
