An entry-level NUC is just barely powerful enough to give a tolerable experience in Windows 10. There are a gazillion single-board computers and Android TV boxes that will run Linux with a bit of hacking.
The modding scene might not have the same level of polish as a rpi - there are ROMs for Android/Armbian/CoreElec but you may be at the mercy of building it yourself, e.g. When the wifi module isnt precompiled for your particular no name OEM device.
