content: I can't believe someone downvoted you. Hell there was more than 2 CPU (though x86 licensing quickly killed that) and GPU vendors (R.I.P. 3DFX, may nshittya burn in hell for patent trolling) back then too. Now days the only many vendor parts are RAM. I won't count PSU since many share the same source components. Motherboards? You do not get a cheap as fuck not name branded motherboard.
