Only the best are maintanence free..

Pros: Good quality Board all together. Been running Mini ITX boards for years and ASRock has been the clear standout
for me. Component placement is reasonable and makes sense. Never a worry about posting no matter what the memory used.
I crunch and run my boards 24/7. No problems with heat degrading board performance. This board like all of my others, is under severe stress and just performs, period.

Cons: Only one Chassis fan port. A fan adapter is necessary depending on your case. Legacy mouse/keyboard Port, Really? Pretty sure the time has passed on that one.

Awesome mobo for itx

Pros: - Lots of features
- Easy to use bios
- looks nice

Cons: The heatsink over the rear components is a little too tall, It could have been slightly shorter and provided better compatibility for low profile coolers. Its also difficult to remove it because its connected to the chipset/m.2 heatsink via copper tube. You either have to remove both or break the tube. Not the best design, but not a big deal imo.

Other Thoughts: I am not going to subtract a star for the con above. To me its a small issue. I was using a Noctua NHL12S cooler.

Great ITX Motherboard

Pros: Solid performance, good overclocking capability. I'm running an I7-9700k at 5.1Ghz all cores. Best performing ITX motherboard out there! Good WiFi. Good VRM and VRM heat-sink.

Cons: only 1x 9pin usb header on the motherboard. Only 1 fan headers supports DC mode, so I'm going to have the split the AIO header between two AIO's. It should work as it is a 2.0 Amp header, but it would be nice if all the fan headers supported DC mode - seems like a relatively easy thing to do.

If you want to OC on Z390 ITX form-factor, no other option

Pros: - Best ITX Z390 motherboard
- No frills OC, just change the core multiplier
- Heat spreaders on the board seems to keep MB temps low

Cons: - ASRock software is not the best compared to what Gigabyte and ASUS has
- RGB options are very limited, cannot control RGB lights to match with CPU temps (Gigabyte and ASUS has this option)
- Heat sinks could be an issue for air cooled setups with wide CPU heat sinks

The Best Mini ITX Board for 9900K

Pros: I'm running the 9900K on this board in the NCASE M1. I'm also using the 545LC mATX Performance Liquid CPU Cooler in Push/Pull. It just works.

Cons: None

Great z390 itx board

Pros: - The best vram module of the first wave of boards.
- Great combination of ports
- 2 M.2 slots

Cons: - Bios continues to be unintuitive
- Huge heatsink could impact CPU cooler compatibility

Other Thoughts: All in all, the best board for anyone who overclocks. However, double check compatibility with your cooler before purchase.
