I just purchased a version of this machine that contained the i7-6700 CPU, 16gb memory, 850 watt air-cooled PSU, nVidia GTX 1080 GPU (1); Windows 10 Pro; 1TB HD; no SSD (I can buy and install one Samsung 256 SSD for less money than their unit price - $100); standard CD reader/writer; and WiFi. Full cost including tax and shipping to CA: $1719.87.
Purchased from Dell. My son gave me a HTC Vive VR system but I had no way to run it on my Mac Pro. This review indicates the Aurora pegged the needle on the VR scoring which is exactly what I wanted. I also wanted to have an easy pathway for upgrading hardware to keep up with what I anticipate will be a quickly advancing VR technology. I believe the Aurora system provides the 'best guess' option to allow future configuration. By the way, my son wanted me to build my own computer and provided all the cut sheets to purchase all the individual components that matched the Aurora. The vendors were all Low Price Leaders. The total for a build-it yourself unit was just over $2000.00. My son is an electrical engineer in Silicon Valley and plays with this stuff every day. This is not to say someone can't do better. Just that the Aurora unit seems to be a very competitive solution and a quality gaming PC.
