I can't install the last GPU because it's pushing down on the headers under it.
Has anyone maybe experienced the same problem and solved it.
In tight motherboard designs like this, I only leave the power switch connected to simplify the connections (e.g. no LED, no speaker)
Sometimes i am able to thread the connection cleverly through the video card cover/heatsink - there is a lot of hollow space in the card to work in and around.
If i'm unable to do this, then bending the power switch pins also allows me to connect the power switch while accomodating a cumbersome card.
btw, there is a 'mining' subforum for hardware related threads and questions.
