Alright, this is just plain clever.
Building a gaming PC, especially something you want to be VR-ready, is a fun challenge. You can try to make your kit as small and compact as possible so it doesn't interfere with your play space, you can go all out and mount the whole thing in individual pieces to your wall, or you can go with something between. Typically, being portable isn't something you can actually pull off unless you want to sacrifice power and jack up costs by going with a VR-ready laptop.
Here's a clever solution from forum member Praxis459 that uses some surprisingly old tech with some cutting edge hardware to create something unique!
What you're seeing here is a Skull Canyon NUC from Intel with a Razer Core packing a new NVIDIA GTX 1080 and an old Motorola Atrix Lapdock. The NUC is a 6th-generation Intel Core i7 PC upgraded with Corsair Vengeance RAM and a Samsung 950 Pro M.2 solid-state drive. While a capable little PC on its own at this point, especially if you want something that can fit in your pocket, you need some GPU in order for this to really be VR-ready. That's where the Razer Core with an NVIDIA GTX 1080 comes in. Razer's kit lets you add a standalone GPU to your PC, so the NUC treats this GPU as though it's part of the system. You get all the power of a gaming desktop in something you can toss into a backpack.
The thing that really makes this build stand out is the Motorola Atrix Lapdock. For the uninitiated, Motorola made these as a way to convert your Atrix phone into something that looked and felt like a laptop. This idea didn't catch on for a couple of reasons, but when you're not trying to connect a phone to this kit, you've got a highly portable 1080p display with a functional trackpad, keyboard, and speakers powered by a battery that will absolutely last you through a whole day. It takes a little work to find the right adapters to make sure your existing HDMI and USB cables can connect to this lapdock, but the end result is undeniably clever.
This is by no means an inexpensive setup, but the end result is compelling if your goal is to take VR gear with you to show off wherever you are. This build was used to put dozens of new people into HTC Vive with no problem, and it not only took up considerably less space than your average VR desktop, it's also much easier to carry around. All you need is power for the NUC and the Razer Core, and you're good to go!
