Here is an Avid S6 Desk that is no longer required. It is perfect condition as it was only used as a display/demo model so has just sat in a show room for around 6 years doing very little. It has never been registered and the little yellow card will come with it. Pic 4 shows the back end minus the four covers, but they are with it just removed for access. This desk is on here on the behalf of Hal Leonard who until recently were a Pro Tools Avid dealer and this (along with an S4 variant) are now surplus to requirement. Obviously this is a large item and fragile item so pickup in person would be preferrable but a courier is a possibility although it would be expensive. I am not an Avid expert, and unfortunately the person who dealt with this side of things is no longer at Hal Leonard, however I will attempt to answer any questions you might have.
