I need some feed back concerning my next purchase which is a Mac Pro. I now have two iMacs and two Mac Books and a Mac Mini on a network, also have a two year old Apple TV. We have lots of old VHS tapes and movies (50 years worth) that I am converting with iMovie and iDVD. I am using Elgato to get the VHS tapes into the iMac. I am burning the movies to DVDs to send to the friends and relatives involved. I have made three projects and burned to DVDs. Basically I am extracting clips of the DVDs by subject and adding titles and some freeze frames. Nothing too advanced. As I climb the learning curve, I may do more. The last project consisted of extracting a 9 minute clip from a 28 minute DVD. I got a message the iMovie would take 8 hours to finalize the 9 minute iMovie. I did not wait to see how long that actually took so just went to bed. The old 2009 2,8 GHz 27 inch Core i7 iMac is not the fastest computer on the block. So I am going to purchase a new lower end Mac Pro: $700 - G-Tech 2TB G-DOCK ev Hard Drive with Thunderbolt 2 $1,000 - Apple Thunderbolt Display (27-inch) $500 - 3.5GHz 6-core with 12MB of L3 cache $300 - 512GB PCIe-based flash storage Total cost , $5,500 I have over 28,000 photos and also use VM Ware Fusion to run Win 7 and some apps. So external storage is important. My Newer Tec external 2TB Firewire 800 mirror drive does have a USB 3 port so that drive should work OK. I am still going to need a DVD burner and SD card reader. One of the questions that I have concerns my USB 2 hub which has three printers and two external backup hard drives connected to it. Will the USB 2 male plug fit to the new Mac Pro USB 3 slot? I have done an internet search to answer this question and have not found it.
