I love the aesthetic design of the box. It's simple, clean, and functional. Given how tightly the crammed everything in, it makes sense as to why they went with nVidia on the GPU. The Titan/GTX 780/GTX 770 cooler is the best blower-style cooler made to date and does a great job of moving the majority of the heat to the back of the card. The rest of the package is not much of a surprise: the PSU looks like the ST45SF-G 450W (best SFX PSU out there), low profile CPU cooler (which is okay since it's not an unlocked chip), GPU on a riser card, and a single 2.5" HDD.
I think the most surprising thing I read in the article is how gaming oriented SteamOS is. The writer mentioned how the OS doesn't even how any type of file browser. Given how Steam is now starting to include non-gaming software on their client (e.g. music creation tools), I would have expected there to be some baseline PC functionality. It's understandable though, as it's probably in Valve's best interest to keep this product as straight forward and user-friendly as possible to appeal to the more mainstream crowd.
