The TARDIS PC
Since the BBC officially licensed the TARDIS PC, Scan Computers was able to build it exactly to scale from the original prop schematics, match the interdimensional police box's precise Pantone color, and load its hard drive with a full Whogabyte of memory to prove it really is bigger on the inside. So get ready to travel the (virtual) world in a sickly accurate version of the Doctor's very own trusty whip.
The TARDIS PC begins as over 45 pieces of high quality aluminum lovingly soldered or stapled or whatever you do to affix lightweight metals together, and imprinted with accurate depictions of the police box's handles and signage. Though the door does not open, TARDIS' inside houses a Gigabyte GA-H61N-USB3, Intel H61 Chipset motherboard with USB3, DVI, and HDMI Support, plus a DVD or Blu-ray drive. Its processor is an Intel Pentium G2120, 3.1GHz Dual Core, with 3MB Cache. Actual hard drive memory weighs in at 500GB, and the computer runs on a Windows 7 Home Premium operating system. So probably you can't use the TARDIS PC to take over the world or hack into and reprogram an army of Daleks to assist you in surviving the end of the world, but...owning one might make you the most geekerific cat in the office and an instant magnet to nerdy hot girls, such as Zooey Deschanel and the one who got knocked up in that movie about teen pregnancy with the guy from Arrested Development.
