I just have a beast of a machine that has more RAM than I know what to do with.
I have a VM of windows 10 that runs in my 4th monitor at all times, it's got 32 gigs of RAM and 2tb of storage. I have another VM that I only run for rendering which uses my whole GPU as passthru. (Having just the 1 windows VM do that interferes with gaming 😁).
I use my NAS for project folders and both VMs have access to the NAS.
