We got a pretty hazy look at the Chromecast's guts earlier this week from the device's FCC filing
The Chromecast's model number is H2G2-42, which as iFixit points out is the common abbreviation for Douglas Adams' classic space adventure book followed by the ""42"", which happens to be the meaning of life discovered in that book. That's either an intentional reference or one hell of a coincidence.
Besides that little joke, there's nothing too surprising about the Chromecast's guts. Maybe its no surprise that the single chip design of the gadget is super easy-to-open, and that once it's open, there isn't much inside to repaired. What else do you expect for $35?
