Eurocom's Panther 4.0 Uses Ultrabooks as Chew Toys
Eurocom's Panther 4.0 is a mobile workstation or a bad mutha-fragger, depending on how you configure it. The only thing slightly modest on it is the 17.3-inch display instead of going all out with an 18-inch LCD. Otherwise, the Panther 4.0 breaks out of its cage with up to an Intel Core i7 3960X Extreme processor clocked at 3.3GHz; up to 64GB of DDR3-1333/1600/1866 memory via four memory sockets; Nvidia GTX 580M or 560M (SLI optional), Quadro 5010M, 4000M, and 3000M options for the professional crowd, or Radeon HD 6990M or 6970M (CrossFireX optional); up to 4TB of storage via four physical 2.5-inch drive bays with RAID 0/1/5/10 support; and a DVD or Blu-ray burner.
It has everything else you'd expect from a modern laptop as well, such as SuperSpeed USB 3.0 support, Wireless-N connectivity, HDMI output, Bluetooth, and the list goes on. There's even a UEFI BIOS running the show on this thing.
""It's a workstation-caliber PC complete with Uninterrupted Power Supply (UPS) in a notebook form factor," said Mark Bialic, President of Eurocom. "It may be large, but this is one extremely fast notebook that replaces desktop based workstation with over 1 hour of built-in UPS battery."

As you would expect, the Panther 4.0 packs a bit of heft, measuring 16.76 inches x 11.44 inches x 2.31 inches and weighing 12.1 pounds. This is, after all, a desktop replacement with attitude.
Eurocom's Panther 4.0 will ship on March 15, 2012. No word yet on price.
