I built my first PC back in 2014 for college meant for simple gaming but now I would like to eventually build a PC that’s great for gaming, streaming and rendering videos for Youtube, then give my old PC to a friend of mine. I say eventually because I’m waiting for the DDr4 ram prices to go down, I am not going to buy ram when it costs more than the CPU I’m trying to get. 
I haven’t really kept up with all the newest GPUs and CPUs coming out so I’m a bit choppy on the quirks and features that come with the newest products out right now. I put this PCpartpicker list together (https://ca.pcpartpicker.com/list/csDrd6) but I’m very interested in making this into a Ryzen build with an R5 1600x or above. I saw OC3D TVs review of the Asus ROG Strix X270 ITX Mobo and I think that would be a great in this build!
budget wise I’m willing to save up as much as I can but I’m wanting to stay around the $1600 CAD price range (I already bought the GPU on sale for $80 bucks FYI), so if you have any tips or tricks for Ryzen that you can tell me to make this build better that would be highly appreciated!
Current PC build: (https://i.gyazo.com/f420d6114fe063c77f5fab958e32451e.png)
Intel i5 - 4670 non K (with Corsair H100i GTX AIO)
MSI Z87 - G43 Mobo
16 Gb DDR3 (4x4gb sticks)
Asus Strix 1070 08G
750W 80B EVGA Supernova
Seasonic 1Tb HDD and 240Gb SSD
NZXT Phantom 410 Gunmetal (soon modding side window to be full window, will post that here once complete 
)
First off don’t pick an X370 board, on ITX there is no difference between B350 and X370. For your use case the CPU should be Ryzen 1700, look out for CPU/mobo deals on black friday/cyber Monday, same with RAM, prices aren’t coming down anytime soon.
The Fractal Core 500 is a nice case to build in.
I’d personally pick this mobo. https://m.newegg.com/products/N82E16813157780
I was looking at that motherboard too but I also looked on the Asus website about the Ryzen ITX motherboard and they are also going to release a B350-i (https://rog.asus.com/articles/maximus-motherboards/bring-ryzen-to-mini-itx-with-rogs-strix-x370-i-and-b350-i-gaming-motherboards/#), I hate to say it but I’m a bit of a “same brand build” kind of guy and I wanted to get the Asus motherboard to match my Asus graphics card.
I do know that the X370 was the odd choice because it was meant for sli or something (like I said I’m a bit iffy on quirks of the new tech), but what other features does X-370 have over B-350?
There is no difference between the boards, ASrock also sells an identical X370 versions. Probably just to sell at a higher price to inexperienced buyers.
Ahh so its just a rename to make it seem fancier, gotcha!
The X370 Asrock mITX board has fancier WiFi, but I’d definitely keep an eye out for that ROG B350 board and subsequent reviews. That’s the one I’m excited about, as I’d also like to build a 1700 mini system.
I use a powerline adapter instead of Wi-fi to get my internet so I wont be needing the best Wifi available, at least that will save me money! buut I wonder if I could use Virtualrouter to make it a hotspot for my consoles and other devices…
