The Lenovo ThinkCentre M70q Gen 2 has an upgradeable M.2 Wi-Fi slot

The Lenovo ThinkCentre M70q Gen 2 has a dedicated M.2 2230 Key E slot for Wi-Fi — typically occupied by an Intel AX201. You can swap it for any compatible M.2 Wi-Fi module, which is refreshing in an era where most small-form-factor PCs solder everything down. A straightforward upgrade if you need better wireless performance.
