Don't know what these server MBs are classified as. Thanks for the help.

In your pictures. The top board is full of value in my opinion. I would contact Chris at Boardsort. I can't evaluate it. The other board. I got a question. Did you remove 2 metal sockets? If so. Metal Multi Socket Server Motherboard.
Here to learn like everbody else.

There's a lot of damage to the Dell board but I can't quite tell what caused it. Fire? Weather? Acid? This may affect the board's value.

CPU2, was it ever installed? The picture is just blurry enough that I can't tell if there are contact pins there. If there are it's a dual metal socket server board, but again that may be affected by the condition of the board.

The IBM, I'm not familiar with and I can't see any model numbers to check. Did it have socketed CPUs or no? If no, I'd go with high Telco. If yes, it'll be one of the server/mobo grades depending on how many of what kind of cpu.
