Thinking of buying a new gaming PC.

My normal gaming PC is old, won't work properly with VR headsets, and kind of... filled up with games that I don't feel like uninstalling. What if I want to play them again later, without having to go through the trouble of re-downloading them?

So since I've used a gaming laptop for so long, I've been thinking of getting something more stationary this time. Like, a nice little corner or room in my apartment just for gaming and streaming shit.

I was thinking of maybe getting the Lenovo IdeaCentre Y710 Cube, but I'm not really that computer-smart. I just know that it looks damn sexy. Anyone know if it's any good, and if it isn't, got any better suggestions?
