It depends: does it look like this and come in a black box with 2 addiitional heads?

If so, then you're good to go. It's "rebuildable" only in the sense that you can replace the heads (technically you can rebuild the heads as well, but most of us simply buy spare heads, lol).
There's also a Smoketech "vivi nova" tank which is actually re-buildable and needs the tweaking. That's the one from the co-ops.
mine is the coop one saddly
