I'd swap out the PSU for a quality 850W like the RM850x, and possibly invest in 3600 CL16 RAM if available. Other than that, looks good. Great motherboard, using it.
Do you even need those extra fans?
The Meshify 2 is already packaged with 3(Dynamic X2 GP-14), so that combined with the 3 on the LF II 360 makes 6 as it is.
