All were used lightly for mining about a year ago, but they've just been sitting in their boxes since.

I have the original boxes for the 290X's. Not sure about the boxes for the 280X's.

I also have 2 990FXA-UD7 motherboards, 1600W power supplies, risers, etc.. These are coming from 2 old scrypt miners, so I'm willing to piece with everything.

Location is 01510 in Massachusetts, USA. Will only do this through a trusted Escrow. Looking for best offers right now.
