At a big event in Las Vegas today, Hewlett-Packard unveiled the world’s first all-in-one workstation with a 27-inch diagonal display. The new HP Z1 Workstation finally brings the convenience and attractive looks of the all-in-one consumer computers to businesses that need no-compromise performance.

The workstation has long needed to be rescued from its desktop tower chassis. But the machines often require lots of modification and a considerable amount of hardware horsepower. It’s a lot easier to put those properties into a tower chassis.

But HP’s new machine has features that accommodate the needs of workstation users. You can snap open the machine so that you can swap out parts and make upgrades without requiring any tools.

The HP Z1 has a cool-looking industrial design that HP has used in consumer models. It features Intel quad-core Xeon processors, Nvidia Quadro graphics, and support for more than 1 billion colors on the display.

The machine is aimed at computer-aided design, digital media and entertainment professionals.

“The revolutionary HP Z1 sets a new industry standard for workstation design, performance and serviceability,” said Jim Zafarana, vice president and general manager at the commercial solutions business unit at HP. “With its game-changing design and an experience that optimizes visual and computing performance, the HP Z1 will help attract new customers and expand our market leadership.”

The system has options for a variety of storage types: 7.2K and 10K SATA, SSD, optional RAID configurations, removable drives (AMO), a multiformat media card reader and optical drives including a slot-load Blu-ray Writer. The display has a 178-degree viewing angle and an in-plane switching panel. It has SRS Premium Sound with dual-cone speakers, an HD Webcam, and remote graphics software. The machine will be available in April for $1,899 and up.
