Equipped with a fairly large heatsink on the processor I have liked a little more space between it and the RAM slot (which almost touches).
A gigantic number of internal SATA port but no external port (damage to my external drive with eSATA port).
The only real issue that bothers me the most and the startup process. Many check takes place before the actual start of the machine (about 5s between the support point on the button and the "BEEP" start BIOS).
Attention to those who buy this product: The motherboard only accepts DDR4 RAM sticks! (Connect DDR2 or 3 DAMAGED motherboard) It does not support all the DDR4. I strongly suggest you get branded RAM to avoid accounting problems. (I had no problem with DDR4 2666MHz 4GB * 4 Corsair).
Otherwise I highly recommend the product. (I have had no problems of delivery)
