Do you know what the surface temperatures on those components were? I wonder if high temperatures led to the failure or if there was some other kind of electrical failure caused by high voltage or current that caused it to burn like that.
OP- you were using standoffs correct? Doesnt look like it at all in that pic
Just standard standoffs...else I couldnt use the expansion slot.
I might consider getting taller ones like they use for open builds...but that would mess up my spacing with the radiators...
I might however make a few more cutouts on the mobo tray and mount some 120s back there.
Yeah from the looks of it the board was too close to the case, now remember higher temps = higher resistance, so if some components were getting too hot it could cause others to get hotter and die.
