This is my first mini ITX motherboard...what can I say...once in hand you can feel the quality and power that you can get out of it, it's heavy compared to its size: quality 10/10! The SSD heatsink is a very nice one, it's a very good one and it's very easy to use, but it's not the only one. The SSD heatsink is massive and makes the TAF!
100% satisfied and recommended
I've been using it for a while now, but it's not really a good idea to use it for a while. The only thing is that the software that comes with it (e.g. rgb fusion) is not up to scratch, poorly optimised and the design is not up to scratch, but it all works fine.
