Connect Apple Cinema Display to iMac

[applemaz]

I have a 20" Apple Cinema Display (M9177LL/A) and need to connect it to my iMac (MB324LL/A).

What cable(s) do I use? The confusing part here is there are 2 flavors of DVI.

I have no idea which one my 20" ACD has nor what the iMac can accommodate.

Should just need a Apple Mini-DVI to DVI Adapter.
