Classic Can a Very Old PC Run Retail WoW?

So had this debate with friends - since World of Warcraft was released in 2004, could a PC from that time that could run it back then, run retail/modern WoW nowadays, or has something about the engine or graphics changed so much that it wouldn't be possible?I get that you can set high visual settings, but is there still an option to set visuals at the state of 2004, so that even potato could run it? via /r/wow https://ift.tt/HYdz7ZM
