Removing redundant wiring from desks is a common task for me. Here I am upgrading the workstation for a photographer from an old Mac Pro that had a cluster in and external drives attached to it. To an iMac Pro and I consolidated all drives in a OWC 6 drive JBOD enclosure and migrated the entire system so that the user will keep his familiar setup and workflow on a new, much faster system.
Sure the it would be better to build s RAID storage system. And if it was my workstation I would have done a clean setup. But I have to keep in mind that what would be the best setup from my professional point of view and the user who wants to remain within his or her workflow that is comfortable from them. And were big changes in workflow and setup are only implements to solve a problem and are not a goal for the sake of it.!
