Is there such a concept as taking a low power laptop or a desktop and installing a bare/thin OS (like a hypervisor?) on it that would then allow you to PXE boot or 'stream' another OS to it? The 'streamed' OS would be a virtual machine running on a VM server? For my use case, I would like to take an old Chromebook and turn it into a thin client that can access one of my many VMs that I curently run on my KVM server (Win10, Win7, etc). NoMachine is a remote desktop software, free for personal use, designed for anyone who wants to access a single or multiple computers using one simple tool. I'm probably using the wrong terms to describe it here. I could take the 230 difference and buy another single board computer to add to my cluster instead.

Im not sure if i need the extra horsepower or not.

The other option i saw is an ACER Spin 514 14 AMD Ryzen 5, 128 GB eMMC, Silver for 579. I've been trying to research a concept but I'm unsure what its actually called and was hoping someone might be able to point me in the right direction, or give me a very basic rundown on how it works and what its called. With the exception of wireguard VPN and (maybe) nomachine it wont be running much else locally.
