Jsaux’s Transparent Backplate for the Steam Deck is $19.99 ($10 off) at Amazon for Prime Day.

But the best part of this excellent deal isn’t even that the user-replaceable shell comes with a heatsink for better cooling, or that it also includes swappable rear buttons to choose your preferred feel. No, the best part is that these shells come in six fantastic colors, and one of them is atomic freakin’ purple!
