This is my first time attempting a Mini-ITX build and I really enjoyed it! I had promised my nephew that he could join in the process of building it, and it was about the least problematic build I have ever completed. It was a few hours of careful work, loads of explanation, and some creative problem solving that payed off well. We wrapped up the build by playing a Lego game. It was great to get to show him that process from parts pile to play'able. Definitely could see the gears turn in a young mind.
I pieced together this build looking to make a portable 4K HTPC that could handle some light gaming. It's also going to have to function as a temporary intermediate PC for a very aging dual CPU Xeon rig. I have been reading reviews for the Ryzen APUs and they were being reviewed as being surprisingly capable as integrated graphics solutions. I was intrigued, and started spec'ing out several potential options with the help of this site. I found the Realan H80S and could see that as a great option to move forward with. Once decided, I just had to generate the funds and look for sales on the parts while doing so.
The largest issues for this build was Amazon sending a 120W power adapter when I ordered a 240W version, and the RGEEKS PSU not being designed to clear RAM. I was able to get about 1mm of clearance between the heat-spreader on the RAM and the PSU's incoming power line connector after trimming off the snap-in clip and trimming back some additional excess plastic from the connector. I then used some electrical tape to hold the connector in place. For the accessory connector, I was able to bend the cables back enough to keep from contacting. Cable management was a little tricky given the space, but was able to make use of some space above the fans and clean up strays with some hook and loop ties.
Haven't dug too deep into thermals yet. The small PWM fans seem to be getting enough heat out of the case for some cooling though. Set them to silent mode in the BIOS, but they're still audible. I don't think they'll be noticeable when audio is playing. Might end up testing how things work with the case fans out of the system at some point, though.
I've used older XBOX 360 wired controllers for the tiny bit of gaming, and grabbed the Pepper Jobs W10 remote for HTPC use. The remote requires a slight bit of a learning curve, but works great! I am thinking to look into wireless XBOX One controllers for the future.
The ASRock motherboard has been working great for me so far! I was able to get my RAM speeds up to 3200 MHz fairly easily in the BIOS. I just needed to set the RAM speed and then enable the XMP profile, the board really took care of all the rest of the settings from there. I had made the decision to go with this mobo based off price / CPU compatibility out of the box / and audio outputs. I am fairly sure this was the only Mini-ITX board in the B450/X470 range with an optical audio output.
The only thing I wish I could change at this point is the mounting direction of the Noctua cooler. Unfortunately there are only 2 options available for mounting given the mounting setup. I could rotate it 180 degrees, but not 90 or 270.
I did run through a benchmark with Cinebench R20 just in case anyone was curious. The system returned a score of 1810 (the 11 year old dual Xeon system scored 1071). Given the use of the system I really don't expect I will try any overclocking beyond getting the RAM up to it's advertised speeds to better the Vega graphics.
I'll have to get more pictures posted as I am able.
