I'm planning a build based on the recently featured Airtop 3 by @AlexTheGreatish which I also loved. The main idea of the system is to be able to run several OSs in order to carry my fully featured case as I move around to LAN parties and occasionally abroad (Router, storage, gaming, media server, workstation for content creation and 3D workloads, etc), being able to just plug and play and have my VPN running and a few Tb of data on a local server ready to be pulled by Windows and Linux.
What I haven't figured out yet is what's best for the virtualized environment and the system as a hole, as I see it is possible to accomplish this with unRAID, VMware, Hyper-V and so on. My experience in virtualization is very little, but I do know I need some kind of type 1 hypervisor, so... a little help in choosing which software I should use at the core of this build? Also hardware suggestions to go along the Airtop 3 are most welcome!
