What are the INTEL part#(s) for the exact replacement for the DELL 4H665 mobo used in the OPTIPLEX GX400 desktop computer? I need the part#s so I can try to find used working boards. firstname.lastname@example.org. It needs to use the same DELL proprietary pinouts for the PSU and front panel power board.
Intel(R) only manufacture OEM motherboards as per the system manufacturer request. The only motherboard that was manufactured for that system is the one installed.
Currently I suggest you to look up fr the part number on the motherboard and try to find it over the internet and see if they are available from a distributor.
