But no.
One slot is crowded out by the graphics card heatsink; the middle slot has a copper heatsink (on the mobo) in the way; the third slot is too narrow on the edge - I almost sliced away some little wires trying to get the Pulsar in there

So that's it for the PulsarII. I've put it in my #2 machine, but realistically it won't see much use. But it's made it's way through *six* PCs in eight years, so I suppose it's had a good run.
