To be honest I recapped the capacitors that appeared to be damaged and fixed the design flaw on one of them (it was mounted with inverted polarity). oh, the one mount between pci slot :D but i think you should at least replace all the cap in the VRM section of the board, when you see one of those …

I think you better find the 50 pin cable that have the termination build-in on the cable. or you can use the 68 pin to 50 pin adapter and using the 68 pin lvd cable with build-in terminator using those cable will eliminate one of the painful issue of bus termination. also made sure to check the blue …

That hole is connected to ground plane anyways so i think you should be fine even with solder connect to the circled part on the board. As long as the via is intact. those small point is to connect the ground plane with the inner ground plane in the circuit board yeah i wasnt sure about that either …
