I know there are a niche of users that see eye tracking as a requirement for their VR usage. Currently, the quest pro is basically the only mainstream headset with this feature, but has many design flaws. I could see this headset being compelling to those people. Other than that, this thing looks too heavy and complicated to be good for PCVR.
If you have low enough latency to their datacenter, it might be viable. You would probably be better off building a cheap PC from a used office computer and a new GPU. Especially if you can get something like a a750 for cheap.
