Budget (including currency): Cheap and cheerfulish, need all pcie lines i can muster for multiple windows and linux vms Country: Sweden Games, programs or workloads that it will be used for: Angular builds, DataBase interactions with SQL Developer, DBeaver on Oracle and Mysql/MariaDB databases. GPU compute is not needed as far as i know at least, unless some of these tasks can benefit from GPU compute. Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): Today we run an older Intel(R) Xeon(R) CPU E5-2696 v2 @ 2.50GHz platform. Single core Angular builds on our projects typically take about ~10 to 15 minutes, getting that down to 2-5 min would be a huge time saver. We have been using HP Proliant G8 and G9 servers with some custom modificiations to be able to run nvme SSDs over a PCIE card so I know its the cpu bottlenecking us at the moment. We have never built a custom server before and could really use some input on what to watch out for. We would like to get hold of a couple of AMD server cpus and then build 2 servers around that. What chassi to choose? What harddrives to use? I dont have experience with newer hardware. Some input on what nvme server harddrives to look for and how to configure them for VM use would be much appreciated. We need to fit things into a 1U chassi, so we need this to be low profile server coolers with fans blowing across all components. I will stop there I am not sure what else to share. I am really looking forward to hear from someone that knows more about the server hardware side of things.

Thanks @enjin_ and @Electronics Wizardy for your suggestions. I was looking for more specific suggestions on hardware and their ability to actually work with passthrough. Like you mentioned @Electronics Wizardy regarding motherbards, that led me to this video by Level1Linux. That pretty much covered all the bases for me, with pros cons on a couple of different motherboards and their ability to passthrough different components. Thanks for pointing me in the right direction!

I am new to tinkering with Linux KVM so I wanted to ask here for advice. Here is what i was hoping to achieve! 1 Linux Host and 1 Windows VM. Asus ROG Crosshari VIII Formula or Gigabyte X570 Aorus Ultra S-AM4 ATX perhaps? Is there performance benefits to either option? Ryzen 9 3900X 64GB 3000MHZ DDR4 Geforce 1070 - Windows VM Geforce 1060 - Linux Host 1 Samsung NvME 512 GB - Windows VM 1 Samsung NvME 512 GB - Linux Host x amount of mechanical hdds for storage, etc. Expansion cards for USB/Sound any extra peripherals needed for the VM. (The x570 motherboards dont have a lot of expansion card slots its the two GPU slots and maybe one more. Is there options other options?) Could I benefit from watercooling all this? Or would air coolers be perfectly fine. I am not looking to overclock any of the components. Squeezing fps out of the gaming experience is not what i need. I run my workstation on linux, use KVM to dedicated CPU cores/threads/dies? To the Windows VM, running Win10 to game on. (I know linux gaming has come a long way but i have no great way of using my own game library on DVDs/CDs/ etc in linux so Windows is better option for me). Today I dual boot my rig with a different HDD when I want to game but instead id like to have both machines running at the same time with a dedicated Monitor and shared mouse/keyboard. I work with java/html5 development, network design and support so I use my linux workstation for that. Using cores and memory available to setup test environments in Virtualbox is something i do on a daily basis. When setting up Linux KVM has anyone seen if the Ryzen CPUs can be allocated like per die so the windows VM got one die and my host the other die. Would that even make things better? So that was a little ramble I am just hoping to get some input from you good folks!
