D2. I've just finished a Ryzen mini-itx build for a friend who likes Dota. It's an NZXT H210 case.
I made the cables myself with some help from @mdpcx. I used 15 AWG for the 24 pin and 18 AWG for the others. The ram is @hyperx low profile DDR4 3200 RAM.
The @ekwaterblocks backplate really tidies up the space and makes it look nice and menacing.
I'm pretty happy with cable management here. I wasn't sure how much space I'd have for the CPU cables in the channel so I didn't bother sleeving them. It actually doesn't bother me and I might do this more often to save time.
The NZXT G12 bracket coupled with a Thermaltake AIO 240 AIO. I didnt want to pay the extra $50 dollars for the NZXT fancy pump block that was facing down so I chose TT. It has a common asetek mount so it all fits together.
The GPU is my Zotac GTX 1080ti that I'm passing off to my friend. I never kept the original air cooler so I opted for the AIO.
The design brief was for something subtle. So I minimised RGB with the Noctua exhaust fan in the top and kept my spray painting to black on black. You can only really see it at certain angles.
Asus B450 motherboard with a Ryzen 5 3600. I took the Wraith Prism from a high end build that's going full custom cooling. The PSU is a Silverstone SFX 650 Gold. This is just in case he gets real about SFF one day and wants to take some of these parts over.
