will I need any special adapters? I have the older 20 inch silver cinema display, will it connect to the mac pro?
 
I think the FireWire 800 port on the Mac Pro 5,1 has backward compatibility to the FireWire 400, isn't it?

Yes, as you wrote, it is compatible, just a small adapter needed fw800 to fw400, and this only if the OP plans to use the monitor's fw400 ports.

You might be able to get it done with 4 of these...

UPDATE: Oops, sorry, I misread this as I though you wanted to plug in a quantity of 20 displays! Nevermind. 😀

wow, I could use 6 monitors with this? thats right, I am not looking to use multiple monitors right now, just one, but maybe 2 in the future.

this got me thinking what if I wanted to watch or work with 4k content on the mid 2010 mac pro?

I have a pair of 20" ACDs hooked into my 2010 Pro, one via DVI and one via a MiniDP-->DVI adapter. They both work like a pair of champs 🙂
