I may have one for sale in a few weeks. I've got an S9 on the way and need time to set it up to run quieter if I can.
My S7LN has been modified (by sidehack) to run more efficiently than the standard model by tweaking the core voltage of the chips. It has only 100 HW errors within the last 27days which shows as 0.0000% on the GUI.
It won't have a psu or a bracket to hold the psu though as I didn't need them in my install.
price?
No idea what they go for so open to offers (plus shipping to wherever you are in the world).
