I think that falls into the workstation category?
Not really, all you need is a beefy PC or laptop. These guys aren't usually running Xeon or Threadripper
Yeah it really sucks that you can't get a normal computer with decent A/V capabilities (or expansion slots to add them) and instead have to opt for a workstation you don't need since "normal" users apparently only use office.
