I have a damaged silverstone ap2 lip as well.

most of the damages came from hitting this metal debris on the freeway. it got caught under my car and damaged the lip in the process. 2 of the mounting tabs are broken, but the lip still holds up (i didn't know the tabs were broken till i took the lip off and replaced it). There's a crack from the point of impact and everything else is scratches under the lip.

I'm in the bay area so if you know anyone going up or down, i can send it with them. prefer not to deal with shipping though since i have no box to ship it but if you want it and want to pay for s/h, i have no problems doing it.

PM me offers. I have no problems keeping it in my garage as well. haven't found a need for a spare lip yet..
