Update: In the end I reviewed this unit here:
A new model Windows 10 Mini PC has hit the market, the Rikomagic MK36S. It’s got an Atom X5 Z8300 with 2GB of RAM at its heart powering the unit. 4 x USB ports (One is USB 3.0) and the usual specs. 32GB eMMC storage, 100Mbps LAN port, MicroSD card slot and full sized HDMI out. It’s good to see it also has Wireless AC, which means you can use the less crowded 5Ghz band which normally performs better than 2.4Ghz and doesn’t effect Bluetooth devices.
Gearbest has it for $113 on sale. I’ll see if can get hold of one for review to check and see how the thermals are.
