I am typing this on a 3GB amlogic s912 streaming box, with ports for USB type A, ethernet and 4K HDMI. Performance for around $40 is what you would expect from a smartphone, albeit the quirks of Android with a mouse and/or tv remote.

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.
