Budget Friendly but still great
The motherboard is micro atx, so some people might not like it. But for the budget its really good keep in mind it only has one 12v 4 pin rgb header.

The BIOS interface is user-friendly, allowing easy customization and optimization of system settings.

Nice piece of gear for my Micro build !! Nice fit into my Masterbox Q300L (no cd/dvd). Came with updated BIOS out of the box (yes, i checked the site). Put my Ryzen 2600 into mobo, worked first time at stock speed (3.4) with my G.Skill Ram and Seasonic PSU. Fine print: Ram worked out of the box. Plug and play. Mobo recognized ram at 2133, quick change in bios to 3.0 - no problems noted. Same with CPU. Fired up at 3.4. Quick bios change to 3.8 - low volts and solid. I'm not an overclocker so happy and easy. Finally, it stock fan is VERY QUIET and super easy install in my case. Finally, finally ... with no cd/dvd in case I opted for a USB Win 10 install. OMG - Never will use a Win 10 CD again. USB 3.0 is SUPER fast - even with HDD. Windows site very easy to make a Win 10 USB. Just need a good Win 10 code for final install. Really really finally - i HATE the LED, PWR switch case connector BS. C'mon ... this is 2018 FFS !! All n all. Easiest build ever. OBTW: like the case option to put HDD on the 'backside' of motherboard area vice an drive bay - much cleaner wiring, very solid, :) Pros: Solid construction, nice layout, arrived with updated BIOS. Cons: -mobo faceplate for case - meh. Not sure if it's the mobo or the case connector but could not get my front case USB 3.0 connector fully flush with the mobo. Works fine, just not a good physical fit, not flush with bottom of the connection - i think it's the case connector, not sure. Diagram on printed instructions for mobo - weak for case connectors / my old eyes. Good piece of gear !!
