Hummm, not sure what mobo this would be but it must be pretty bad if it forces you to "force" a card out of its slot.
My mobo, you just press a little tab with your finger that allows you to pull the card out.
And, yes, you could possible break something on the mobo, probably the latch that was holding it in place or worse. Id say if you were going to do it, be careful.
It's not so much the Mobo, but the gigantic cooler I have which leaves me no room between the cooler heat synch and the card itself, so I can't get to it from that side, and the card spans over two slots the other way, so I can't get to it from that side either
The right way to do it would be to disconnect the cooler, then get to it, but I'd rather not if I really don't have to.
These clips are the worst thing ever created, especially when I can EASILY pull the part of the card that is closest to the back of the case partially out of the slot with minimal effort. So it's not like that stupid clip is serving any useful purpose, I mean if it held the entire card in the slot, then fine, that would be something, but it can't even do that!
One thing's for sure, once I get this card out, easy way or hard way, I'm breaking that piece of crap clip right off. Should've done that when I bought the mobo in the first place.
