ELSA Announces Thunderbolt PCI-Express Expansion Box

Run out of expansion slots in your system? Bulky graphics cards eating into smaller PCI-Express x1/x4 slots for devices such as PCIe SSDs, sound cards, and other expansion cards? ELSA has a solution for you, provided you have a Thunderbolt port to spare. The company announced the MAGMA ExpressBox 3T, an external add-on card enclosure, which talks to its host over Thunderbolt.

The MAGMA ExpressBox 3T encloses three standard expansion card bays, with two open-ended PCI-Express 2.0 x8 slots and a PCI-Express 2.0 x4. The three can be used for PCI-Express add-on cards of nearly every electrical configuration. The enclosure packs its own 250W power supply. It features two Thunderbolt ports, with which it can be a part of a larger Thunderbolt device daisy-chain, letting you conserve the limited number of Thunderbolt ports in your system. The enclosure is PC and Mac-compatible. Measuring 371 x 200 x 110 mm (WxDxH), the enclosure is made of aluminum panels with a steel frame. The company did not reveal pricing or availability information.

What's really neat is when ThunderBolt sends data to the cable, it actually two different streams of data. There is a multiplexer/decoder on both ends of a thunderbolt cable that multiplexes the signal on each end shoving more data over thunderbolt. If you ever notice why your ThunderBolt cable gets warm (I do, I have one at work for imaging our newer Mac laptops,) that is why. The cable does a little more than just enable data to be sent back and forth, it's changing it to send it back and forth. :p

ALso explains why the cables are so expensive. This is much better than DisplayPort cables that cost a lot, but for an unknown reason.

Something like this would be awesome if you did a miniITX build with 1 expansion slot (used for graphics card) but still wanted to use a pci wireless card and a soundcard to, if the price is right. Surely this product is going to cost a fortune though :(
