This motherboard is well made... and heavy. Serious thought went into the placement of the massive aluminum heat sinks on it. The inclusion of 3 (total) M.2 were well placed as to not interfere with other component placements. A much need heat sink for the PCIe 4X4 drive slot is incorporated seamlessly into the design.
None as of yet (and I don't expect any) but I will amend my review should something arise.
I have owned several ASRock motherboards in the past and have never experienced a failure. This will be my workhorse for years to come.
This review for ASRock review rebate program (but I would have done it anyway)

This motherboard was defective from the start. Would not POST. Company states that warranty wont be honored for any damage caused by the customer installation but the wording is such that they can claim I installed it incorrectly and will deny the warranty regardless of if it is true or not and I wont be able to prove otherwise. Its just my word against theirs. This is the absolute last time I buy ANYTHING from this company and will tell everyone I know not to buy anything from them.
