You are beating your head against the wall Scat. We are old school, redundancy, efficiency and cost effective are not as important as bragging rights.
Just like "Trading computers", some need state of the art, (although they can't articulate their actual needs), custom made etc... When in actuality for most a mid class system is more than sufficient. (it must be better, it cost 5x the price of that dell refurb)
Regarding CPU coolers, I like
Noctua, low profile version is fine for typical system, reliable and silent. worth the extra $20 to the cheaper options... I replaced all my intel coolers with noctua.
Edit: yes, I use dual matched cards on all my systems which require 3+ monitors, dedicated dual head card for the others. I don't use onboard video unless no other option. No need to share system ram for Video.
My first system dual monitor system also was Matrox. Do you remember the ability to flip to portrait view? That was cutting edge tech back in the day... Portrait view was the catalyst for second moniter now that I think back...
Kids these days are spoiled... lol
