do you get memory and voltage regulator heatsinks with this?
I think so yes, there were certainly a number of 1cm square headsinks with sticky tape underneath, but i didn't end up fitting any of them onto my 3870 since it already had a couple of large heatsinks covering the memory chips etc.
As for fitting an 8800GT,
their website says that it does, but i guess these things always depend on good case airflow too.
I would also add that this thing is an
absolute beast in it's size, and is by far the tallest thing in my case, apart from possibly my AC Freezer 64 CPU HSF.
