I could be at this persons location in an hour or 2 but it doesn't seem they are motivated in selling being details are lacking on the gpu rigs.
Simply saying "gpu rigs" is not enough to go on to make an offer.
Which cards, which models, hash rates? too many variables
No cards are being sold.
It's very clear. I am selling the frame, PSU, motherboard, and risers - everything but the GPU
