Tried to Divert a SATA port lacking issue with a PCIe substitute.

I'm currently trying to resolve a Sata port issue on my board, (and by Port issue, I'm referring to the lack thereof, considering it only has 2 ports on it.) My original solution was using a PCIe Sata Expansion card. Only the problem was my board has a PCIe 1.0, and not the 2.0 I had apparently ordered. None of this was cheap, and I'm about to flood my amazon with refund orders. What Can I do to find, an EXACT similar motherboard type to the one I already own + 6 sata, and more PCIe expansion buses at the south of the board? I really enjoy this board for only the fact that it also sports a wireless NIC slot built in, but honestly at this point, replacing the motherboard entirely, is seemingly where I'm headed now.

I would suggest you look into the Asus Motherboards most of them have supported M.2 PCIe 3 NVME with 2 slots for the last 3 years or so. From the Z97 through current models. If you go for an older model like the Z97 be sure to check the newer ones supported NVMe the original versions only support M.2 SATA and would us up two of your 6 SATA ports. Just check spec's before you buy the manuals for most MB are downloadable
