Ordered this computer from B&H Photovideo online. It arrived in 4 days, and was very well double-packed. I immediately installed a Samsung Pro 840 SSD. This computer is FAST ! I have found no problems with it, other than it only having 6 GB of RAM. Which will be remedied after the Christmas Holidays. Installed the Mac OS Maverick and encountered no problems at all. Also installed a PCI card that provides 4 USB 3 ports which are very fast also. I use the system for photo and video work primarily. I recommend this computer to everyone wanting a fast and very expandable computer.

Had a 2 generation ago Mac Pro- this one is night and day different. If you do video, upgrade to 2 card option. Unbelievably fast render times.

Amazing performance in such a small machine. I am contantly jumping from place to place, so the small form factor and the amout of power a huge advantage

Upgrading from the old mac pro was the best thing I did for my business. It is so fast and quiet, and B&H delivered it to me in lightning speed. Thank YouB&H!!!!

I purchased this MacPro Quad core to replace my aging MacBook Pro 2011 model. It is used primarily for music production. This is my first Pro Mac since owning a G4 tower years ago and I am very pleased with my decision. I was on the fence deciding between the latest iMac i7 with Haswell CPU and this one and I'm glad I decided to get the Pro! The benefits over the iMac are: it is expandable to 64Gb RAM (compared to 32gb for the iMac), it supports 4k displays (even though I have no need for one now, I'm sure prices will come down and. unlike with the iMac, I'll be ready), and the upgradable Xeon CPU. In addition, the ECC RAM and Xeon CPU provide a level of stability that desktops just do not. The only things weighing in favor of the iMac were: the amazing 27 display and the relative cost for a somewhat comparable configuration. Overall, though, the Mac Pro is worth the extra expense for longterm upgradability and stability. Highly recommended!

I will call it the mother of all computers

I'm a professional editor waiting to update my aging 2008 Mac Pro. Though incredibly expensive, I saw how the new Mac Pro was optimized to work with FCP X and knew it would work with my workflow. Being part of my livelihood, the purchase was deemed by me to be worth it. It is incredibly much smaller and lighter (which when I have to travel to location is greatly appreciated), and quieter. In my office where there are hard drives whirring, that is a welcome respite. As Apple has designed the new Mac Pro as the hub, this purchase may require additional considerations such as having to buy external storage such as USB 3.0 or Thunderbolt drives, a PCIe chassis (for those with cards needed for video ingesting like the RED Rocket card or AJA cards), an e-SATA Thunderbolt hub, a DVD / Blu-Ray burner, etc. It can be a bit of a wire jungle behind the computer but that was always the case with me and my last Mac Pro. It is worthy purchase for me, but I realize that if I did less processor intensive tasks like word processing, e-mail, internet surfing, media consumption, etc. I would definitely not find this worth the price and just opt for the excellent iMac series for far less. However, if you're a video editor, 3D artist, serious photographer or anyone who has to render images quickly and efficiently, then I would seriously give this a strong consideration. Personally, I'm loving it. One thing I do wish the Mac Pro came with was bigger internal storage (I got the 1TB internal SSD) as I had to take my rather large iTunes library and put it on a 2TB external USB 3.0 drive, but maybe one day someone will release larger capacity SSDs.

I'm so glad I bought this Mac Pro before they all disappear. It is fast, quiet, energy efficient and handles everything I ask it to do speedily and with no problems whatsoever. This is undoubtedly the best computer I have ever owned. I never realized just how good the Mac Pro is until I had this one. It has my unqualified commendation as an outstanding product, bought from America's finest professional media equipment dealer.

Blazing Speed! I use this computer for movie production. The SSD is woefully small. Store applications ONLY on the SSD, so that you have enough room for current video projects. Store all data files on other drives. I am hoping for a drop in SSD prices when the new MAC PRO is released.

I love how it is built, its versatility, its expansion slots
