After previewing the model at WDDC 2013 and setting its price in October, Apple's new Mac Pro will finally go on sale tomorrow.

Apple CEO Tim Cook took Twitter to share an image of the Mac Pro assembly line in Austin.

"We have begun manufacturing the Mac Pro in Austin," Cook tweeted. "It's the most powerful Mac ever. Orders start tomorrow."

The tiny desktop computer, which looks more R2-D2 than PC, will ship with the latest Intel Xeon E5 processors, up to 64GB of RAM, dual AMD FirePro graphics chips with up to 6GB of dedicated memory, and up to 1TB of PCI Express solid-state storage.

While Apple has paid a lot of attention to the raw power inside, the chips and memory are stored within a cylindrical housing that is coffeemaker-inspired. With the outside casing removed, it looks like a miniature robot, a huge change from the previous Mac Pro design that featured anodized aluminum in a traditional tower casing.

The latest Mac Pro certainly does not look like the average desktop PC, and it is largely designed for professionals who need access to speed and storage.

Starting at $2,999, you will get a 3.7GHz quad-core Xeon processor, 12GB of RAM, dual FirePro D300 graphics, and a 256GB SSD. A variant with a 6-core CPU, dual FirePro D500s, and 16GB of RAM is also available, priced at $3,999.

The new Mac Pro is made in the United States, and the tech giant claims that it will be as quiet as a Mac Mini during use. It is officially available to order tomorrow from Apple's retail and online stores, and ships with Apple's latest OS X Mavericks version 10.9 operating system.
