With the Magma ExpressBox 3T there really is little reason to buy a Mac Pro. Use your PCIe cards with an iMac. This is great news for musicians wanting to upgrade old tower macs but keep their DSP and interface cards.
“ExpressBox 3T provides an ‘outside-the-box’ solution for using PCIe® cards with Thunderbolt-equipped computers. High-performance flows are possible by connecting a Thunderbolt equipped computer to a Magma ExpressBox 3T containing PCIe cards such as video capture, media transcoding, audio processing, and fast data storage. And because Thunderbolt is also based on DisplayPort technology, you can daisy chain a high-resolution display with your Magma ExpressBox 3T.” – prweb.com
