I got a dell poweredge 2900 in from UPS today and there was some damage to the box and the server inside. When I opened the PE 2900 chassis one of the motherboard heatsinks was ratting around, as well as the little white thing that it clips into.
The dell hardware owners manual lists just about everything else on the motherboard, but I don't know what the heatsink is for but I think its the southbridge, and how I can go about fixing this - or if the whole motherboard has to be replaced. (See photos) I tried putting the little while thing back in the holes it goes in but it doesn't seat all the way down. I have not tried booting the 2900 yet.
Any ideas on how I can fix this, can it be fixed, or am I looking at replacing the motherboard?
