There's this one as well costing around £350.

Is the extra cost worth it to run Kodi?

Absolutely not

If you really need to upgrade that Celeron, do it to the Pentium version for an extra €15. That gives some extra single threaded performance.

If you order from a German company you'll get the unit for £275

If you really wanted am i3 have a look at this

Thank you to all three for your comments.

It seems the Pentium would give best performance vs. cost provided it was used with the most efficient Display Port to HDMI adaptor, which Matt has kindly described to me in another post.

Thanks again, the willingness of people to give assistance is much appreciated.
