Use your boards single system 4 pin fan header and a SATA connection from PSU to run this hub and up to 8 fans.

Are you sure that's your Board?
That's a mini ITX board you're planning on putting in an ATX chassis,
If so I can only see two fan headers on the board, and one would be taken up by the CPU cooler, you'd have one header to power 5 fans, which isn't reccomended,
you could use a molex fan controller or something to power those fans though.

Why put an ITX in an ATX case, gonna look really strange! Why not get an mATX or ITX case instead.

Yes, your ITX board will only support 1 Fan (excluding your CPU fan) You can buy Y splitters and connect up to 3 maybe for fans of one fan header but will all run the same as controlled by one fan header. You can also buy 12V fans to run direct from PSU but not very good as cannot control from BIOS or software, run at full speed.

Most ITX boards only support 2 Fans headers (CPU _ Case Fan) Some higher end, like Asus ROG Impact support 3 fans plus CPU fan.

Best bet is just get some fan splitter cables OR go for an ATX/mATX board that will support potentially up to 6 fans.

SR-71 Blackbird has the right solution. Your mobo's only SYS_FAN header does appear to use proper PWM Mode to control 4-pin fans, so a 4-pin fan Hub such as Blackbird suggests is the right way to control many fans from one header.

HOWEVER, that Hub will only work if all your case ventilation fans are of the newer 4-pin type. The problem is that many cases now come with 3-pin fans, and plugging those into any 4-pin fan header results in the fan's running full speed all the time., with no control. 3-pin fans require what is called Voltage Control Mode. The website for the case you specified says it comes with five 120 mm fans pre-installed, but does not specify which models, so I can't tell from here which type they are. The site does say the case includes its own "fan controller", but what that means apparently is that you can manually set your fans to High speed, Low speed, or Off. This is nothing like automatic control by a mobo header. This info also suggests that you MAY have to do some fiddling around with the wires for the pre-installed fans so that they can be plugged into a standard fan header.

IF your case fans are really of the 3-pin variety, there is one Fan Hub on the market that CAN control 3-pin fans while using a mobo 4-pin PWM Mode header for its control signal source. It is the Phanteks PWM Hub. Apparently is uses the PWM signal to create its own group of six 3-pin fan headers operating in Voltage Control Mode, so it can power and control any mix of 3- and 4-pin fans. That might be what you really need.
