I have a titanium Z60m with a T500 motherboard bulging out at the seams. But you wouldn't want that.
I've seen some decent Z61t listings on the feebay like what jronald posted, incl. an untested but booted-to-BIOS one (in good condition, too) for I think $40? But that's been gone for awhile I think. They pop up every now and then, but you have to look for awhile.
If you want the titanium look you could also do this ->
