GF2 Ultra & GF3 were the first Geforce cards designed to have ram sinks in reference format. As such I suppose nVidia choose to redesign the PCB with all the Ram on one side for cost and or assembly reasons.
Here's some pics of the finished card including a pic of the back, blocks are retained with screws using nylon washers for PCB protection, no gluing or card modification required.
Nice to have the forums back BTW
