A $600 PC with a dedicated graphics card is probably going to have a worse CPU than an M2 or M3 Mini, and probably no Thunderbolt. You would only be cross-shopping a PC like that with a Mac Mini if you were thinking of graphically-demanding productivity work, like video editing or Blender. If it’s for gaming then the Mac wouldn’t be in the running at all.
Friendly reminder that we have already identified and largely fixed a climate change problem, the depletion of the Ozone layer, and we can fix other problems too:
