Hi. Is there an adapter or way to adapt PCi to PCIexpress? Some people have thousands in their peripheral equipment, graphics or audio professionals for example. We eventually need a new Mac Pro. I found this one on the Web, I wonder if it would work for Mac? I wonder if it would work for, say, a 2011 or 2012 Mac Pro desktop: allow us to adapt a PCI card from an older machine. Some of us have thousands in our peripheral PCI stuff. Thanks so much for any replies. Really appreciate it.
