You are welcome, the swappable fans makes very easy
to clean the GPU...
All Z170 motherboard shares the M.2 with something...
That is why needs to read the manual or some good review...
The Z170 Classified have a very good implementation, but sadly only one slot for M.2 is capable
to receive the SSD.
"The Z170 Classified has two M.2 slots, or maybe just one, as the second slot is “Key-E” type.
M.2 was supposed to fix the confusion over mSATA and mPCIe, but splitting the M.2 market between
Key B and Key M for storage, plus Key A and Key E for regular PCIe devices, seems designed only
to replace one form of customer confusion with another. While the naming convention leave much
to be desired, EVGA has done its best to describe these interfaces within its manual."
2 M.2 4.x slots (both must run at 4x)
3 SATA3 6.0 Gb/s for 2 HDs + Blu-ray
Look at the Z170 Extreme7+ https://de.pcpartpicker.com/product/Tx648d/asrock-motherboard-z170extreme7http://www.eteknix.com/asrock-z170-extreme-7-lga-1151-motherboard-review/all/1 http://asrock.pc.cdn.bitgravity.com/Manual/Z170%20Extreme7+.pdf
using 2 M.2 4x SSDs will disable 4 Intel SATA ports leaving you with 2 Intel SATA ports + 4 ASMedia SATA
ports(no RAID and maybe no optical devices). https://rog.asus.com/forum/archive/index.php/t-28796.html
If you plan to RAID(Intel) the HDs can only use the 2 remaining Intel SATA ports, the problem is that the ASMedia
SATA ports may not work with the Blu-ray, so must use one Intel SATA port to the Blu-ray and the HDs to
the ASMedia SATA ports, but with no "hardware" RAID.
The new Z270 chiptset may enable you to use two M.2 SSD 4x and 4 Intel SATA Ports at the same time.
