Well I just had a quick look at mine and cant see anything that looks like a screw that might short onto a circuit board but it's not clear which 2 screws they mean. It could also be a batch issue with only some cases using a too long screw but who knows. I've emailed them anyway to get in the system but I don't intend to stop using but will limit its on time to when I'm next to it.
The way its described and from some of the customer reports/reviews it sounds like it would occur on first use rather than after a while (mines a couple of months old now)
Just had a look at mine, the screw is straight onto the circuit board and then through the steel of the chassis. Cant see how the screw length could cause a short. At first it sounded like the screw was so long that it was touching a circuit board behind it but there is only air behind the tip of the screw.
Could the head of the screw be too big? Or overtightened damaging the PCB?
Either way it seems to be a instant and rather spectacular failure rather than one caused by time so I won't loose sleep about it bursting into flames. However will fix this in the fullness of time!
Edit: A bit of reddit reading suggests it might be too large a diameter screw which is digging into the PCB rather than just going through the hole (as per mobo screws).
I reckon it's the head. If they had used a smaller round head (m3 perhaps, like the other risers I have) it would have been fine. If that is a gripper screw it could be damaging the PCB area on the riser if done up too tight.
I have some nylon screws I tend to use to fix risers. Hard to cause a short with nylon.
My repair kit just arrived but obviously took the best part of month. 3 nylon screws and nuts (1 spare) and clear instructions. My screws were bloody tight and it produced a grey/silver dust on removal. No doubt this was PCB residue. Easy fix but make sure to blow out the dust clear of the case on removal of the original screws.
Yeah saw that this morning. Kinda confirmed the various suspicions I had read. I'm fine with plastic screws as it will probably need a pcie 4 riser in the near future
