- Great motherboard with one major factor to consider when building in small ITX cases - Madimetja, 27 February 2022
The motherboard functions great without any major problems except for the fact that the sata ports point to the side and not up. This is a non-issue on regular sized motherboards but on an ITX board this might pose a major problem, such as in my case where i could not use regular sata cables in my NR200 due to the proximity of the power supply to the motherboard. I am forced to get low profile right angle cables in order to get around this issue
- Great Buy - LINDSAY, 11 February 2022
When I ordered this motherboard, I was surprised at the amount of features this ITX motherboard has. The best greatest thing is the hi speed WIFI adapter.
