considering for this build, there had to be custom made hardware, I was most intrigue in 2 things: the water cooling system which was custom and one thing it wasnt said: VM software used. I saw the benchmark ones video but he didnt really go in dept in terms of software base.
32gb per VM, basically a slight upgrade to my ROG. My ROG has been modified thats why.
This video purpose is just to show that it is possible to run 7 vms in 1 huge server style machine, since CPUS are specific for servers.
I personally run 2 VMs + Diablo 3 on my machine at real time, each vm with 2 cores and 4gb RAM and I have no issues when running D3. If I swap to VMware however that is where the struggle comes in. I suppose the video itself is running the server edition of VMware.
