Whitey,, you are correct in your information!
Dell does customize their MOBO for their cases,, I bought a machine with some RDR ram was more cost effective to replace the internal parts than to purchase more RDR and then when I went to do that ,, I was told and found out exactly what you ask,,
Dell customizes their MOBOS in their systems,,, Bastage!
So,, It was a new build for me,, new case,,came with PWS,,400w,, and New MOBO,, pulled the HD's and all the internal cards,, and now have an expensive husk of a Dell sitting in my basement,,
Glad I'm not alone,,
