I travel occasionally, so i decided to build carry-on friendly VR-PC.
Processor: Intel i5 6500.
i3 (2 cores * 2 threads) is a good option but i need to use VirtualBox, screen capture and video rendering.
If you're planning gaming only - 6100 will do the job and save you 100$. Most games do not utilize extra cores, VR is not really CPU dependent.
i5 (4 cores * 2 threads)
6400/6500 - not a big difference but 6500 wins in $/fps comparsion.
Box version for sure - no overclocking planned, ITX friendly low profile, PWM capable fan for ~5$ is totally fine.
Motherboard: MSI gaming B150i Pro AC .
"AC" means a bundled m.2 wifi card. If you buy it separately, it usually costs 20-30 usd, if you buy AC version, it costs ~15 usd.
-10-20% cheaper than identical Asus gaming board.
-wifi/bluetooth module. MSI Marketers claim it to have super low latency.. sounds like bullshit to me.
-M.2 SSD socket. M.2 is a way faster than normal SSDs. this motherboard claims to have 32gb/s bandwidth cap, pretty much PCI-e 3.0 M.2 maximum. It supports up to 2280 cards, because it's placed on the back of the motherboard.(22=W, 80=L. there are quite a few standards so just having m.2 port does not mean you can plug fast SSD drive)
-"military grade" capacitors - IDK if it's just a marketing trick, however i'm old enough to check capacitors type on motherboards, when i was younger, i fixed quite a few motherboards by cap replacement.
-USB 3.1 gen1 ports. Zero problems with Oculus + 2 tracking cameras.
Just choose 14/15 CAS timing 2133 memory. Patriot/G.Skill/Kingston, depends on your local store prices.
I strongly recommend you to get a m.2 32gbp/s 2280 ssd card for system and apps.
I recommend something semi-modular/modular, 400w would be more than enough.

If you cut CPU to 6100 and motherboard to ASrock h110 - you will get 600$ VR PC with just a few fps loss in games.
AMD processor will save 50-100$ more.
