I've been doing some research to get a Egpu so I can have a powerful laptop with good battery life and still be able to come home plug it in an use my HTC vive. I've been doping some browsing and I can only find pre-built enclosures for thunderbolt 3. I have seen you can use mini PCI if you just want the cable but not Thunderbolt. I was rather hoping to be able to custom build my enclosure so if i could find a thunderbolt 3 to PCI-E 16x cable, i could do the rest myself. Is this actually possible considering this.
