hi,
my selfbuild is much older, not fanless, but provides for 6 SATA Ports + a single old parallel IDE (which is sufficient for System partition...)
currently I use 3 SATA Ports for a Raid (which also results in a good throughput of the Network Interface)
So about 4 years old, still about 45% capacaty free and still has the ability to be extended with no effort.
So choosing a MoBo with more Ports and more PCIe Ports is a favor if you want to be future save
