So, I am in the process of getting my build finished up. I have been looking at external PCIE enclosures so I can use a PCIE to M.2 Sata/NVME adapter for copying OS's and copying hard drives. I would also like to run the Asus Essence Internal Sound card in an external enclosure connected via thunderbolt on my Asus Z370i motherboar. I was curious if anyone has attempted this even with different equipment and what results they got. I've included links and pictures below.
