For fun I've been thinking of a very small form factor gaming build <$850.I likely won't build one but it would be fun to make a "console"-like ultra portable system that will kick PS4 and XBONE in the face. Requirements: Mini-ITX; Water cooled. AIO 120, 140, 240, 280s are all fine. It won't have a crazy heat-producing CPU. Whatever the case supports. RX 480 4 or 8GB which gives us respectable 1440 gaming and VR. Reliable SSD; >= 8GB RAM; <400 watts; Looks sharp; AMD or Intel CPUs are fine. However Intel offers all their sockets for mini-ITX while AMD only gives us FM2+ and not their flagship AM3+ (dicks). Due air flow I would go with low profile ram heat spreaders like the g.Skill Ares series. I've done budget builds for family but they've all been full towers and before the introduction of the RX 480. My go-tos are the Corsair Carbide cases (200R is phenomenal with all its options, roominess, and quality) with an FX 8350 and R7 270 with a recent build I did. The RX 480 really improves on those specs. However with a Mini-ITX it's a no-go on the FX series. I'll post a Partspicker link soon of what I've got.
