The Transparent edition of the nubia Red Magic 5G went on sale on May 31 and sold out fairly quickly. This video shows what you're missing out on if you didn't get one. The transparent back panel and the pulsing LED really gives it that "gaming PC" look. Also, this is one of very few phones to feature an integrated fan for cooling. You can see that demoed in the video with a piece of dry ice. Of course, the transparent back makes it possible to see the "smoke" make its way through the phone, a really cool visual. If this tipped the scales for you, you'll be happy to hear that...
