I bought one of these and trying to install esxi 8.0.1 custom iso with community network drivers and can't get it to recognize the NICs.  Any ideas? With this not run ESXi?

@gra-rgirard I wasn't sure on the network adapters on this one, but GMKtec often configures these with Realtek NICs which are not supported in ESXi. You will need to use a USB network adapter for it to recognize the NIC. Ironically, VMware supports Realtek-based USB network adapters, so most of the current ones you can find on Amazon or other online sources will work. 

I know @malcolm-r picked up one recently for ESXi that was 2.5G. He may be able to give you the model that he pulled the trigger on. I have a generic 1 gig adapter made by Anker that works as well. Also, just to be aware, ESXi 8 includes the USB network drivers which is pretty cool since this used to be something you had to create a custom ISO for.

@brandon-lee Thanks for the reply Brandon!  What was throwing me off was before i made the purchase i asked their support what nics come with the K8 since i was aware of the Realtek / ESXi issue and they told me it came with Intel nics.  After trying like hell to get ESXi to install i then switched to proxmox and saw that they are in fact Realtek and was not happy as I never would've bought it if they told me the truth from the beginning.  Thanks again for your reply and all your videos.  Great for building out the home lab.
