Honestly, when it comes to your specified amount of Cores & RAM you’ll have tough luck. Got myself a MiniPC with 5700U and 32GB of RAM, two 1TB SSDs (mirrored) and 3 NIC but that was still 500€ after waiting for a decent deal.
Even buying a used PC off eBay will most likely cost far more if you insist on your specs.
Dad allowed me to watch Species. Had to sleep in my parents’ bed that night. Mom was FURIOUS :D
