The Apple Set Top Box is an unreleased project by Apple. There are a decent number of prototypes floating around nowadays, and I was able to get cap reference values and a logic board photo for the STB3 revision from jajan547 on 68kMLA.org.
These have 33 caps total on the logic board, so if you have one, you're going to want to get them changed. They're from the era where you can bet on finding leakage.
