Hello! I'm on PC Part Picker and I got this compatibility message:

"The motherboard M.2 slot #1 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."

I'm unsure if this is going to affect me or not because I am inexperienced and I do not know if I will be using the M.2 slot. I really appreciate any help/assistance!
I also get the message "Some physical dimension restrictions cannot (yet) be automatically checked, such as cpu cooler / RAM clearance with modules using tall heat spreaders. " and I don't know how or what I am supposed to measure to make sure everything fits. Thank you for your time and help!

This is what I have set up so far:

The board you're looking at has one port on the SATA connectors shared to an M.2 port on the board. That being said, when you have a SATA based M.2 drive in the M.2 slot, SATA port 1 will be disabled. If you have an NVMe PCIe based SSD in the M.2 slot, SATA port 1 will be available. You're good to go with the current storage setup though I'd ask you to look at the Samsung 970 Evo Plus or the SN750 from Western Digital as opposed to the SN550 as the primary SSD.

You don't have that many SATA drives listed. There are 4 additional SATA ports. and SATA 1 is only disabled if you have a SATA M.2 device. You don't.
The Block diagram on page 21 of the users manual explains most things.
