Old timer re-entering kodi!! 1080p/4k capable cheap box please!!

Hi, I’ve bought a panasonic 902b and could do with a box to run kodi on again which is a bit more mobile. I have a gaming rig which will usually playback content but would like a nice tidy mobile solution until i get my setup properly sorted.

Whats a cheap 1080k bluray high bitrate (I’m talking 30gb rips or Bluray ISOs) from an external hard-drive which u guys could reccomend?

I do have a macbook pro, I am tempted to just hook this up to the TV for now but its quite unintuitive remote wise and the wires make it all quite messy.

Thanks,
