Suggestions on birthday present for 13 year old boy who (almost) only interested in computers?

[Nena7]

My god sons birthday is coming up and I don't have a clue what to give him! He is very bright and seeing since it's 13, I wanted it to be a bit special.

Any ideas?

A Game gift card spot on, money combined with the power of choice. Special n their eyes!

A Raspberry Pi (if he doesn't have one already)? Or an Arduino? I guess it depends what you mean by "interested in computers"
