Just an FYI. My cable arrived within just a few days.

On a related note, I'm curious why it was decided to use a Display Port interface. I found it very hard to find any LCDs with display port interfaces. All the LCDs I've looked at have either or both HDMI and DVI interfaces.

To answer my own question, we have successfully used the following cable sold by tvcables.co.uk:

Displayport to HDMI Cable 3m (£15.99)

• Premium displayport hdmi cable for transferring high-bandwidth, uncompressed digital video, multi-channel digital audio and control functions.
  
  
• DisplayPort 1.1a HD 1080p compatible.
  
  
• Supports resolutions up to 2560 x 1600 and 1080p.
  
  
• Supports 8 channel, uncompressed 24bit audio.
  
  
• Bandwidth: 2.7Gbps per lane (total10.8Gbps).
  
  
• 10 year warranty against manufacturing defects.

Display output selection always demands a trade-off between current display availability and support for advanced features. There are several design considerations for display interface selection in Intense PC and fit-PC3:
(a) Currently, display port is the most straight-forward way to support high resolutions.
(b) Display port can be easily converted into legacy display interfaces with commercially available adapters such as http://www.google.com/products/catalog?q=displayport+to+vga&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&tbm=shop&cid=3893997268446097757&sa=X&ei=FebyT5vPIYTAhAfl-7TPCQ&ved=0CGEQ8wIwAA and http://www.google.com/products/catalog?q=displayport+to+dvi&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&tbm=shop&cid=9923238192836032208&sa=X&ei=J-byT8NFkJvUBevCtbAJ&ved=0CG4Q8wIwAA.
(c) Going forward, it is likely that in a year or so most new displays will feature Display Port input.
(d) Original DVI connector is two large for a product like Intense PC.
