!rant, I have a couple of sky hd+ boxes knocking around, we've cancelled our sky subscription as we're big on netflix and amazon prime instead and sky don't want the boxes back. I was going to take the hard drives out (1 TB each) as i could use some more external storage for my work and pics, but before I do so is there anything I can do with the boxes instead?

Afterall they have a circuit board, memory and a chipset, can I replace the sky OS with something else?
