StreetDeck.com makes everything. StreetDeck is the brand name that applies to both the hardware and the software.
Some StreetDeck hardware is just rebranded and available under other names, but sold as a StreetDeck product after it is certified to run the StreetDeck software. Other hardware will only be available exclusively as a StreetDeck product.
The only StreetDeck products currently available that I can answer questions about are sold at the mp3car.com store.
The Intel Ultra Mobile PC was designed and manufactured internally at Intel. We are working with many different companies, Intel included, to get them to help us make some cool StreetDeck systems.
