Hi Phil
UK based, as is the customer i'm looking to help in this situation.
Although i believe there is a little confusion on the customers behalf since i've logged this, i have the MS120-8LP at home at have explained that this wouldn't normally be racked on a wall in their environment anyway. They normally just place it in a small cabinet without the need to rack, so not sure i have a problem anyway more really.
Happy to have any further feedback though.
Thanks Phil
