The hardware is in excellent condition, as it was run in a cool environment with nearly no dust. All GPUs, motherboards and PSUs were cleaned with canned air anyways.
Open to negotiate if you're interested in higher quantities or want to buy everything.
Generally I'm only interested in selling the parts in bulk and for GPUs I'm looking at a MOQ of 50.
