Just ordered a gaming PC from CyberpowerPC: Asus TUF Z270 Mark2; Intel Core i7-7700k 4.2 GHz 8 Mb cache LGA1151; 32 Gb DDR4/3000 MHz dual channel; EVGA GeForce GTX 1080 SC2 icX 8 Gb GDDR5X; 250 Gb WD Blue m.2 SATA-III SSD; and a 2 Tb WD Black SATA-III mechanical hard drive. I chose all the preceding online from among the customization options offered, and they're being installed by CyberpowerPC prior to shipment. My question: once I receive the PC, can I add a 500 Gb Samsung EVO 960 NVMe PCIe 3.0 x4 in the second m.2 slot and a 1Tb Seagate Barracuda SATA-III mechanical drive?

The motherboard M.2 slot #2 shares bandwidth with a SATA 6.0 Gb/s port. When the M.2 slot is populated, one SATA 6.0 Gb/s port is disabled.
The Bandwidth is shared between the M2 and Sata slots and it is prevalent on the entire range of z270 platform and cannot be avoided.
Dont see it as a problem, as you wont end up using all the sata and m2 slots at the same time anyway, unless you are hell bent on doing the same.

Yes I read that too, but am wondering about PCI-lane issues and/or using up all SATA3 ports. I'm completely new to all this but I see from other forum questions that it seems easy to cause some kind of problem that would prevent boot-up or that would steal PCI lanes from other devices, etc.

Thanks, that would be all I'm adding to the box, other than some USB external devices. I'm hoping to keep Windows 10 on the pre-installed SSD and then put Mac OS X on the SSD I'm adding.
