I'm a dummy. Thunderbolt 3 to Thunderbolt 2 egpu iMac late 2015.
I don't even now if i can put this here, sorry btw.
I might get an iMac late 2015 21.5 inch for free and want a gaming pc. I'm thinking about buying an Aorus Gaming Box with the GTX 1070. The problem is, the pc doesn't has any thunderbolt 3 ports, only thunderbolt 2 ports, and I saw some adapters from Apple. Would it work with an adapter? I'm a dummy in this area so I need some help. (srry for my english grammar)
Yes it should work, you just lose out on a few features like USB I believe. Try searching the build guides for that enclosure and TB2.
