GX400 uses proprietary 24 pin 330W power supply. The GX1 and GX110 etc use proprietary 20 Pin 200W Power supply that's not the same.
Socket 423 Intel 850 chipset motherboards and GX400 use RDRAM which is not made for decades now. Absolutely no reason why any of these single core Pentium 4 Wilamette systems are worth trying to get working.

The only reason I am doing this is that I have a supply of internal parts, my parts pile. I am trying to put a few of these together so I can give them away to seniors like myself or those who cannot afford a computer. For this use these users would be happy to have a free working computer good enough for basic use. Are these models the entire list of these parameter? I was told the 423 was the first generation of the P4. Correct? Only used for a short time?
Yes but socket 423 systems used RDRAM and need CRIMM's for the empty socket. GX400's also have proprietary Power supply and other parts that are neither easily found nor are they current enough to be of interest. Much newer Pentium 4 based chips can be had for very little.
Entire assembled and working units can be obtained with windows 7 for $100 which is the cost of the software alone.
Its like you are saying you have Hubcaps for a 1937 ford F150 and want to know the 23,542 parts that go into making that truck because you will be able to assemble it because you have the hub caps. You may be able to do this but the cost of obtaining each part will be more than a used current ford F150.
The cost of ram and power supply and motherboard parts like fans and heatsink etc will be more than the cost of an assembled working system and that DOES NOT include windows which for these systems would be windows 98 or windows 2000 not even XP all of which are End of Life End of Support.
