Connecting Apple 20" Inch Cinema Display to the Mac Pro 2013

[iMore Question]

My Mac Pro 2013 just arrived. I am having trouble finding a way to connect my 20" Apple Cinema Display. The display has an ADC connector - 30 pins in a block of three rows of ten and four additional pins on the end. I'm having a great deal of difficulty finding a way to accomplish this. The friendly Apple Support person was unable to help as Apple no longer supports this display. Has anybody managed to configure this? After spending $4500 on the computer I'm not really in the market for a $2000 Apple monitor. I guess if this can't be done, does anyone have experience getting a Dell (or other) monitor to work with this computer?
