I really enjoyed working with this MB and it delivered absolutely everything I needed for the build. Standout features are two NVMe M.2 slots and decent wi-fi / Bluetooth with a snazzy external antenna included in the box. I was going to be a bit cheeky and dock one star for the GPU retaining clip which jammed and then broke off as I was removing my graphics card, but that may have been my heavy handedness.

This is probably the best mini-ITX Ryzen mobo on the market right now and from what I can tell the build quality is fine. It had everything I need and the built-in wifi is working great. I like how they positioned the various parts of this mobo; in particular, it's the M.2 SSD slot was very efficiently positioned.

There is only one chassis fan slat, one CPU fan slot, and one AIO Pump slot, but given this is a mini-ITX build, that shouldn't be an issue. I connected one exhaust fan to the CPU slot and one exhaust fan to the chassis slot. Then the radiator/CPU cooler was connected to the AIO Pump slot and I was able to dynamically adjust the AIO Pump settings in the Bios so that fan utilization % changes based on temperatures and doesn't run at 100% constantly.

Support on the website could be better on the instructions for doing certain things, such as updating the BIOS could be more clear. That said, the utility that comes with the mobo made updating the drivers painless and easy.
