I don't know if people are actually doing that, but it's crazy that it's plausibly possible to do so profitably. For example, this prebuilt desktop from Maingear costs $2,500 [0]. The notable components are a AMD 5900X and Nvidia 3080. The 3080 alone has been sold for $2,000-2,500 (MSRP $699) on eBay. The 5900X has been sold for $600-700 (MSRP $549).
