IF you are talking about the "Trade-in" [my term] program, I am aware that the "Gift Card" program has been subject of many complaints - UK program too.
I did not recommend that. I merely cited the existence thereof to give context to the rest of my post. In fact, I said:
... I cannot find a way to trade in an Apple TV via that portion of the website though ...
Makes the issue moot, methinks.
If you are referring to the "Re-Cycle for Free" program, I just linked directly to the page, as it was a little convoluted to find via the http://store.apple.com/us/browse/reuse_and_recycle page (No AppleTV choice!).
But the Recycler will take darn near anything – Free.

PS: We have now spent FAR more time on this subject than the value of the OP's AppleTV Gen1 (one has to put a $ value on one's time).
I think it would make a nice coaster or paperweight.
Conversion to the traditional Fish Bowl doesn't look like it would work out as well as other Mac models I've seen.
