A:Answer 1) The processor does not support VR - if this is your preference, I would consider one that states "VR Ready".
2)There are plenty of great heads out there pending price range. Search for your price point and check the reviews specifically for sound quality and durability.
3)Keyboard and mouse are good, but not great. They look great with the bright red lighting, and are a good starter set. I used for about 5 min in startup, but I opt for the Logitech or Razor brands myself for durability and weight. (not to mentioned I already own them)
4) There is a remote to control the lighting within the case, but the red fan and case display cannot be modified. Plenty of room for additional fans/lights.
5)I'm sure there are after-market options, but not familiar.
