As an insult, Artie calls Fargo "Bismarck" which are both cities in North Dakota. Bismark is also Fargo's bowling nemesis from Area 51. This is something Artie very likely knows.
According to Wikia, the thing in the box where Claudia and Fargo were hiding is Rumpelstiltskin. Saying his name out loud gives him control over you.
This Warehouse 13 crossover episode with the TV series Eureka is the first of three Eureka-Warehouse 13 crossover episodes. The second is Crossing Over (2010). The third is Don't Hate the Player (2011). The characters Douglas Fargo and Claudia Donovan are in all three episodes.
According to the boot-up screen, the new warehouse computer has eight 500 petabyte drives (4 exabytes, or approximately 4 billion gigabytes of storage). Oddly enough, the processor runs at 4500 mHz (4500 millihertz, or 4.5MHz, slower than the original 1981 IBM PC) - probably a typo.
The Falcon Scott protocol, which freezes the Warehouse in subzero temperatures, is a reference to Robert Falcon Scott, a noted Antarctic explorer who led the ill-fated Terra Nova expedition in 1910-1913. All members of the expedition, including Scott, died.
