If you still want the box to connect to your Shadow instance without an existing PC, you can rent it for $10 per month or purchase it for $140. It could be particularly useful for a TV for instance.

The new Lego Batcave Shadow Box set is set to retail for $449.99 or £349.99 if you're based in the UK. So it's not the cheapest set out there, but then again, it's designed for those aged 18 and ...

Shadow Ghost might be easier on your wallet, too. It'll cost the same $140 as the Shadow Box (which is going away), but it should consume three times less power than its predecessor.

But the new box, the Shadow Ghost, features a much more low-profile design, coming in at just 182 x 123 x 50mm.
