Question Build my own PC inside a Corsair 2000D Airflow for running Linux VM's for Education and Self Training

[owegen]

Hi everyone, I need your help. I want to build my own PC and use it as a "mini-server" for running different Linux VM Machines for tests and educations.

Any advice for motherboard, power supply, ... to install in a Corsair 2000D Airflow?

The biggest resource for VMs is RAM. Put a larger percentage of your budget into RAM. CPU cores can be shared, RAM can't.

32 Gb?

 

[kanewolf]

32 Gb?

That would be my minimum recommendation. But it depends on how many and how large the VMs are.

 

[USAFRet]

32 Gb?

Consider each VM as a whole PC.

What amount of RAM will each need?

Minimum, 8GB. So, running 2 of them...that is 16GB right off the top.
Leaving 16GB for the host.

Adding a 3rd simultaneous VM...now you're starving the host of its own RAM.

I've personally had several instances of the VMs using 20-24GB.

I don't think I'll start more than 2 VMs at the same time.

what about the storage ? SSD or HDD?

 

[COLGeek]

what about the storage ? SSD or HDD?

SSD. At least 1TB. I agree on 32GB (2x16) as well.

Have you looked at pcpartpicker where you can build your own system?

What will these VMs be used for?

What about the Moterboard and CPU?

You prefer Intel or AMD? Or no preference?

it doesn't matter.

Yes, I read that.

I should have been more clear.

What software might be running?

Running just the Linux OS to learn it is one thing. Minimal resources needed.
Running Linux to learn the vagaries of AutoCAD or Blender is quite different.

Sorry, you have right...
I will run XCP-NG and from there start Linux Machines (Ubuntu) and learn how Docker, Kubernetes, etc. works..
If everything works fine I'll install Truenas SCALE and use it as my main Storage
