Just bought a dual CPU Mac Pro 4.1 for $689. That feels pretty good, right? Currently own a 5.1 6-core 3.33GHz with a Accelsior_E2 and R9 280X. The idea is to go 3.46 dual CPU and sell of the 4.1-->5.1 3.33GHz while I keep Accelsior and 280X. Essentially I just swap trays between the Mac Pros and sell the 2009 case again, now as single CPU. At the same time I want to try the internal 5.25 PSU route in order to open up my options for a 2nd graphics card. It's fine with me to drop another 280X in there. Seems like good value. I'm not sure if how the cables get routed from the DVD bay down to the g-cards. Do we have any guides/good ideas for that?
