  The ODriod is £100 cheaper than a Chromebox, The AMD system costs (to within a few pounds) as much as the bottom end Chromebox. Except all of the HP Chromeboxes have an Intel Celeron 2955U which is half as powerful as the AMD Athlon 5350. I've also specified a 120GB SSD in the AMD system and the HP Chromebox's only have 16GB of storage.
  
  

If it's for the living room, why not consider swapping out the case and PSU for something smaller with an integrated PSU? (Something along the lines of this? There are a fair few knocking about so have a browse.) - You'd need to swap out the 3.5" disk for a 2.5" one however.

Unless you have ample space for the 130 then by all means, ignore me. :)

Damn it. Look at this case, think I should go for this instead?
