Do not forget the eMMC card adapter that then piggy backs into a microSDHC to SD card adapter. And that whole setup plugs into a PC.
16GB may be overkill unless you have a pretty large Library. Its whatever you are comfortable with in the end.

I've also been told this £17 OSMC RF remote works with LE boxes:

Other options if you wanted more BT and WiFi connectivity are the £95 MINIX U1

The only issue is you not be able to use your Harmony IR remote as @kszaq the LE developer uses the alternate IR AMLogic receiver method. A Wireless MINIX A2 remote would definitely need to be purchased.

Then there is also the £90 WeTek Hub that will also run LE really well. Plus give you Android HD/4K Netflix & other DRM streaming Apps in an easy Dual Boot setup.

You don't actually need much RAM at all for LibreELEC Kodi streaming. It and the C2 are LibreELEC Reference Hardware. IR Harmony will work with the Hub.

LibreELEC can be flashed to internal eMMC memory from a running micro SDHC card with AML S905/X Android boxes only. Not S912.
