I've played with a couple of these machinist boards before, they came in a parts bundle i purchased. The biggest issues are support, the BIOS isn't amazing, and they will sometimes freeze when coming out of sleep mode. So long as you're not using it for anything mission critical, and are good with using hibernate instead of sleep, it'll be fine. I cant speak to how long it'll last, but it worked fine as a board to mess around with. Also I wouldn't expect, nor recommend much overclocking with it. These boards are basically made from recycled parts, e-waste gets sent to china, and is stripped down, and then sorted. What they do then is rather than crushing and recycling a bunch of good chipsets and components, they rebuild them into cheap boards. They mention B85, C226 and Q85 as the chipsets used, meaning its luck of the draw. I love the ingenuity behind products like these, basically giving cast offs a new life.
