thanks, yes i can get Fintech/gigabyte.   question regarding risers..as these gpu's are pcie4 do i need corresponding pcie4 type risers or can one settle for the standard pcie 3 risers?  guessing from a mining view there's no difference

This doesn't make any sense since PCIe 3.0 and 4.0 have the same pinouts. The standards are differ by increased bandwidth (data transfer rate). You can even use the chinese noname motherboards. However, branded motherboards (ASUS, ASRock, Gigabyte) will be more high-quality but also more expensive.

just get what is easily available, easily warranty-able in your location.

thanks for all input, appreciated!...once assembly is complete will update with pics.  if/hope things work smooth plan on adding another 7 cards but will have more confidence after this is up/running.
