Build looks excellent. I would probably go with the 1650 super and I would definitely bump the storage up (I'm guessing the 20 vms are going to be using shared storage?)

Definitely want to change the cooler to the h115i rgb platinum. The PRO is the old version.

Firecuda is definitely the fastest.

If it's out of stock just remove it and buy one ready for the system arriving. It's very easy to plug in :)

Will a 1TB SSD be big enough? At 4GB RAM per VM you have the potential to run 31 VM's (leaving 4GB for the host). With Windows 10 alone needing a minimum of 20GB space that isn't a lot of overhead. You could look at combining the SSD and HDD using tiered storage in Windows (10 has it as well). It's kind of like a hybrid SSD but much better performing as the SSD part is that much bigger.

You're right to up the RAM - you'll become memory constrained way before you become CPU constrained for sure but I wouldn't worry -too- much about the speed of it for your VM's.

You don't say what hypervisor you plan to run to host your VMs but Windows 10 Home does not include the Hyper-V role - you need Pro or Enterprise for that. https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/quick-start/enable-hyper-v


My Hyper-V server runs full desktop experience Windows Server 2019 with Hyper-V installed. Currently 13 of the 48 VM's are active and this is the performance tab of Task Manager:

The VM's never miss a beat even if I fire all of them up - they are as responsive as being sat in front of a dedicated machine.

They have 68.5GB of RAM assigned to them (the running VM's).

The server is a generation 8 (so two full generations old now) and the RAM is 1333MHz DDR3, albeit ECC RDIMMs

It has 2 x Xeon E5-2620 Hex core multithreaded CPU's.

Not the highest performing machine by a long stretch but it copes really well as a virtualisation host.

I like VMware Workstation but bear in mind it's a type-2 hypervisor whereas Hyper-V (whether installed as the standalone product or via a role in "full fat" Windows) is a type-1 hypervisor.

That said, VMware has some distinct advantages - it can pass through a much wider range of hardware such as webcams and even GPU passthrough. Of course, the downside is it takes more resources than a bare metal (type-1) hypervisor.

You -really- want the virtual machines on SSD if you can. At the very least, tier it - Windows will move around the most used files onto the SSD and the less used files onto the HDD. It all appears as a single drive.

20 VM's @ 25GB each is 500GB so that is 500GB for your host and any applications - probably fine and dandy :)

With 128GB RAM you could assign 6GB per VM and still have 8GB for the host which should be fine.

Just out of curiosity, how safe is it to leave a computer on 24/7 - I would quite like to remote in from abroad to this computer, and it would mean preferably keeping it on at all times
It’s fine, you’d need a VPN to be able to connect to it externally.

Mines been running 24/7 for a number of years.

Safe depends on the angle you are aiming for.

If you mean power wise and component wear etc, it's perfectly safe. Some of the most detrimental effects come from switching the PC on believe it or not. It's designed to operate this way. You could use a WAKE on LAN effect if you wanted though.

Security is another kettle of fish though. You need to ensure that the security for your tunnel is tight. This is where most ransomware attacks occur.
