I purchased 2x2U chassis off eBay which came with BPN-SAS3-216EL1 backplanes.

On both of them, I found one capacitor that fell off at different locations. No biggie I guess.

I ordered two refurbished backplanes also from eBay and when they arrived today I noticed that one of them had capacitors resoldered at exactly the locations where the capacitors fell off on my original chassis.

I inspected the area closer and both capacitors sit on top of some screws in the chassis. Anyone else noticed this / had this issue ?

I installed the intact backplane that arrived today and it doesn't appear to be touching those screws but still, it's a pretty huge coincidence, right ? Exactly those 2 capacitors fell off on 3 different backplanes!

Is there any danger of those capacitors shorting with the chassis ?
