MSI states their VR One is the world’s lightest and thinnest backpack PC system with high performance, which makes sense considering the utter lack of competition in that area.  It may also claim to be the most expensive, as the price ranges from $1700 to $2300 in cost; [H]ard|OCP tested out the high end model in their recent review.  Inside is a Kaby Lake Core i7-7820HK, 16GB of 2166MHz DDR4, dual M.2 storage drives, and the mobile version of the GTX 1070; certainly enough to power a Rift or Vive.  The battery life is more impressive than you might expect, starting from 92% it lasted 1 hour and 37 and from 96% 1 hour and 41 minutes, with 2 hours required to recharge the battery over 95%.  It is an investment but being able to experience VR without tripping on cords is an attractive proposition.

"The MSI VR ONE is quite simply a full PC that comes in the form of a backpack that allows you to connect your HTC Vive or Oculus Rift for a "wireless" VR experience. This VR ONE unit packs a GTX 1070 laptop GPU to hopefully supply us with the needed 90 frames per second performance required for a perfect Virtual Reality experience."
