I really like the AtGames Legends Gamer, but the "Core" unit - the one that sits in your entertainment center - has a power-on ring light that is very bright and which becomes annoying very quickly. The only way to turn off the light is to turn off the Core and the only way to do that is to unplug it. (poor design, AtGames!)

I made a little cover that slips over the Core unit and blocks the ring light - but has an opening that mimics the usual power-on indicator light of most of your other electronics.
