Whether you're editing feature films or scoring them, composing symphonies or visualizing mass spectrometry analyzes, Mac Pro makes it easier than ever to create your personal dream machine: a powerful system that not only meets your needs today but, thanks to an ingeniously designed enclosure, expands easily to meet tomorrow's challenges as well. The easy-access interior of the Mac Pro feels like the well-organized workstation it is. No rat's nest of components here. You don't need to turn the system on its side or struggle to reach into awkward spaces to make changes. Just remove the side panel for instant access to everything. Slide out the processor tray to add memory. Slide out drive bays to add storage. Slide a simple bar to change up to four expansion cards at once. And with plenty of I/O ports both front and back, you'll have room for all your external devices. When it's time to upgrade, a quick slide of the retention bar frees up the four expansion card slots for easy access. Thanks to a thumbscrew PCI bracket, you can swap out cards without any tools. The Mac Pro comes with four drive bays for an enormous amount of internal storage. For faster access to your data, you can also configure your Mac Pro with up to four solid-state drives. The bays are direct-attach and cable free, so it's easy to add or remove drives. Just attach the drive carrier to a drive and slide the drive into place. There are no connectors or cables to contend with. Lock the drives with the side door latch, and you're done. Install more memory in your Mac Pro in a snap. Literally. The easy-access interior lets you slide out the processor tray in one smooth motion, then simply snap new memory into place. You don't have to dig around inside the computer or wrestle with wires or cables. The Mac Pro is built with a recyclable aluminum enclosure. Aluminum is very desirable to recyclers, which means the raw materials used in the Mac Pro can be reused in other products. Apple also simplified the internal design, replacing over 6 feet of cables with more material-efficient connectors that allow easy disassembly at end of life. In addition, one of the few remaining plastic assemblies in the Mac Pro is made from postconsumer recycled plastic.
