I want to build a computer that could run up to 75 vm's. I have no clue where to even start with this. The vm's will be windows 10-32bit

75 virtual machines.

You cannot do this on a single host PC.
Period.

Even at the bottom level of RAM for Win 10, that will consume 150GB RAM for those VM's.

Now....what are you actually wanting to do?

And what are these things doing?

What are the rest of the specs for your i9 system?
running a java program, that does some random stuff. This is more or less just for testing. I also have 64Gb of ram. And NVME ssd. each vm has 1 gb of ram

Depending what will stress more--cpu, memory, or storage, I would know several ways to do this. It will have some compromise though unless you have unlimited funds--cheap, fast, or quiet--pick 2.
CPU gets stressed the most and i don't care about it being quiet

But enough free time to create an account and post this question.
OK.


In any case...you cannot do "75".
I mean they take a while to turn on because i have to wait for the cpu usage to go down on the previous ones and im trying to use my computer right now. haha
 
The only CPU remotely capable of doing 75 VMs would be a Threadripper 3990X. And that's most likely not going to be enough either.

If you want to do 75 VMs that do more than just simple tasks like routing and firewall stuff, and actually crunch numbers quickly. You'll need several tier 1 hypervisor servers.

What about cost? If cost is no object then a new 2u rack server with dual processors and a chunk of ram will do it well.

If cost is a concern, a Dell R720 with dual e5-2695 v2 processors will give you about 24c/48t to work with. You could load it up with about 128-256gb of ram and enough storage for your VMs and have decent performance to work with assuming you will not have all 75 VMs maxing out their assigned hardware simultaneously.

Since there's usually an evaluation time period, I'm sure setting it all up wouldn't be a licensing issue.
With Win 10 Home or Pro, there is no "evaluation period". There is either Activated or Unactivated, from Day 1.

If it were Server, there is generally a 90 day eval. But any of the recent flavors of Server will NOT run in 1GB RAM.
 
The cheapest answer is to buy several used 2U servers. DL380s. It won't be quiet and it won't be energy efficient, but it would allow you to scale the number of instances as large as desired.
I don't think you would need more than one server as long as you get one powerful enough. The newest generation 2u servers like the Dell R740 have up to dual 28c/56t (xeon 8110) which in a dual config will easily handle the requirement. Of course, you're looking at higher 4-figure budget for something like this.

But there is 30 days for running in unactivated mode.
False.
I have a Win 10 Pro, Unactivated, running in a VM to test exactly this.
See what happens over time.

This was installed on Dec 8 2016. Over 3 years ago.
Still running exactly as it did on Day 1.

That "30 day" was a thing with 8.1 and earlier. Does not apply with Win 10.
