Pros: Six SATA-III ports. Two m.2 sockets - both support PCIe and one also supports SATA. 16 PCIe lanes instead of the typical 8 found on Intel 110 chipsets. Four memory slots for up to 64gb RAM (Supports DDR-2133 on Skylake procssors and DDR-2133/2400 memory on Kaby Lake processors.). Has D-sub, DVI-D, HDMI and DisplayPort video jacks onboard. Four USB 3.0 and two USB 2.0 ports in the back - also has connectors for two additonal USB 3.0 or four addtional USB 2.0 ports for front panel connections. Separate PS/2 keyboard and mouse ports. Can access BIOS upon bootup with a USB keyboard. Very easy to setup out of the box - Two mounting screws are included for the m.2 sockets, comes with two SATA-III cables, and has discs containing all the necessary drivers (including USB 3.0 drivers for Windows 7) and tools for flashing BIOS. BIOS management is straight forward and easy to use/configure. Supports Windows 7 right out of the box - no BIOS flash necessary. Onboard Gigabit Intel chipset. Includes a 5v PCI slot.
Cons: Typical junky Realtek ALC887 onboard audio chip - only useful for playback. Non graphical BIOS - has old style BIOS interface. Not a big deal to me, but this may not be appealing to some. Silk screening for connecting HDD, Power LED, etc. is not clearly marked - can be confusing to determine which way to plug connectors in (as it turns out they should be plugged in horizontally). No PCIe-x1 slot above the PCie-x16 slot. One x1 slot will be covered up by a modern dedicated GPU card and the other is too close to the GPU's intake fan(s). If you plan to install an PCIe-x1 card and also have a dedicated GPU card installed, you will need an extension cable for the x1 card.
Overall Review: Overall this is a very solid and reliable motherboard. Its performance has been flawless thus far. I have purchased a second Prime B250-C/CSM for another build and would recommend this to anyone that doesn't need to overclock their CPU.
Pros: The board seems to work OK. CPU tends to run cooler than with my previous board
Cons: This commercial board has an old-style BIOS (Aptio 2.17.1246) that has no option for upgrading. ASUS customer service keeps assuming the either this board had a graphical BIOS or that it has an Advanced tab upgrade option. The included driver disc does not have BIOS updating either. This is a serious security problem. The computer gets stuck at the BIOS splash screen occasionally during resets. A full power cycle is needed.
Overall Review: After going back and forth with customer support for a week, I am returning the board.
Pros: We have purchased 50 of these, and they have performed well.
Cons: It seems that this motherboard is end of life

Pros: Has all the basics for a business workstation.
Cons: No RAID support
Overall Review: Even though the chipset is supposed to support RAID functionality, this board does NOT have RAID support. The sales page did not claim to support RAID, so I can't slight ASUS for that. But I was basing my purchase on Intel's chipset support page that said the B250 chipset offered RAID. Well, I guess it's optional as to whether the motherboard manufacturer actually includes that option. Oh well, I set it aside and ordered an H270m-plus to serve my purpose for that machine. I'll sit on this one for a non-RAID build.
