Asus launched the PN50 mini PC with Ryzen 4000 processors in 2020. Now, a device described as the bare-bones version of its successor, the PN51, has appeared on the website ProShop. According to this listing, its chassis has not changed in 2021, and thus still boasts a configurable port that can add anything from a DisplayPort to a second RJ-45 to the device.
