Funny this should come up, as I am in the middle of writing something in just that style. Can't think of a published adventure that is heavy on that, though.
You know, it's interesting that in all the time Privateer Press was publishing 3.5 encounters and mini adventures in their No Quarter Magazine (a good seven years or so), I can't recall them publishing much of anything that had fights or encounters with Steamjacks or other clockwork creatures. Which was/is their bread-and-butter.
I looked at a lot of these suggestions and just started to work out my own campaign as well. I figure there must be a Golem master's keep out there somewhere... I went and designed a clock work wizard tower that spun like the gears of a giant clock.
