These are great. If you are looking for a first class experience go with a known brand. But if you are looking for an inexpensive, good board that boots and you can use old parts with to make a powerful little systems, these boards do the job.These are sold under many listings and brands with just a few differences. I bought 2 different ones and the only changes were the colors. I went wild and put 18-core Xeon E2695s on the, paired with 128MB of ECC DDR4 server memory. They run great. I use on to host ProxMox and another as a test box for whatever I want. They are rock stable.Complaints? Sure

It's junk. I had high hopes to reuse a good Xeon, but the board refuses to POST less than a month into use. Very light use, too, maybe a week total. The jury is still out on other Machinist boards that I purchased, but this one, stay away.
Works well in my old server. Would buy again! Came well packaged
Great board, but directions weren't given in the box. Also, had to really crank the screws on my radiator to get it to fit on which wasn't the most comforting process. Features are good. Boot speed is standard. No lighting really.
Motherboard did not post sadly. Motherboard looks good that's the only thing it has going for itself.
For all the issues I had gone through getting this build working, the motherboard contributed to none of it. It was mostly my stupidity and failure to double check the contents of what I thought was a Windows install USB.To all the people that's saying there's no manual, there is. It's on the listing page. Look for it in the "Product guides and Documents" section in the listing page. Yes, I understand that you aren't shipped a physical one with the mobo. For how much this mobo is, I'm not gonna complain.The supported RAM speeds is DDR4-2133 and DDR4-2400, and nothing else. I'm not kidding.My O
Despite the price and no name brand it just works great
Didn’t know amazon fulfillment or manufacturer was located in the middle of the ocean. That’s the only reason there would be this much rust. Do not buy. I feel like I need a tetanus shot after opening this.
