@kijetesantakalu042, Depends on if your PC could do it. There are settings to use the CPU natively and adjust the graphics memory which does quite improve it a bit.
But why go through the effort of having Linux inside of a VM, whereas you could have a multiboot installation or replace your pre-existing OS with Linux.
@Izanagi_No_Okami, You can, but best to look at the specs before buying them. Some have eMMC chips soldered to the mobo that you cannot remove without hot air, and unpopulated SATA ports.
