the good old days of Dell prebuilt

Had a XPS 8700 the owner wanted to extract a i7-4770 so the rest was given to me. I put a i3-4130 in, no power.

figured it was a bad mobo, although cpu socket pins not bent

the i3 stays cold to touch.

in the good old days of Dell XPS 8000,  oem board is cookie cutter micro ATX, standard 4 or 3 pin fan header, standard 9 pin front panel, removable IO shield, I happen to have an HP 700 desktop that works 100%, but I dislike the ugly boring HP case.so I simply pulled the hp board and dropped in the 8700.  All wires plug in naturally.  The only ridiculous thing of HP idiosyncrasy is they insisted on using torc screws.  So the hp board boots immediately in the 8700 case, even the miniPCIe WiFi card can use the 8700 antenna.  Well, one draw back is that the 8700 psu 12V cpu power connector is precut short for 8700 board, and the hp board cpu socket is at a different real estate location, so the cable is a bit taut stretched.  Might look for a 12V extension cable.  But overall wish to see Dell some day go back to using standard mobo form factor and standard headers.
