Magma Introduces Thunderbolt PCIe Expansion Box

by

For users who need a bit more expansion for their Thunderbolt equipped Macs, Magma has introduced the ExpressBox 3T. The 3T is an expansion chassis with three PCIe slots for "outside-the-box" expansion.

The 3T can be used to connect PCIe cards for video capture, audio processing, data storage or whatever other needs a user may have. It works with any Thunderbolt equipped Mac and daisy-chains with the new Apple Cinema Display with Thunderbolt that began shipping this week.

Magma has not announced details on pricing or availability, but has a form for interested buyers on its website.

Not Shipping

Looking forward to the day when ANY 3rd-party thunderbolt peripheral manufacturer announces their pricing.

Or even SHIPPING!

I'm getting tired of all these articles on non-shipping Thunderbolt products.

Price is going to be just a hair out of the stratosphere if we go by their magambox expresscard 3/4 box price.

I think this will bridge the gap between iMac and Mac Pros more in terms of expandability but I'm still waiting for the new Mac Pros to be announced as I want to pick one up!

At that ridiculous price, you might as well go ahead and buy a Mac Pro by the time you add it on to the price of a Mac Mini plus a graphics card! Given I can buy an entire Hackintosh with a high-end card for almost the price of just that expansion box, I say the heck with them. They're obviously price gouging the living daylights out of Mac owners that they figure are so used to getting screwed on hardware prices that they won't even notice.... :rolleyes:
