There are plenty of others. Thermaltake has lots of them: Armor, Shark, Kandalf, TaiChi, Circles, Eureka, some of the old Xasers, etc. Silverstone has several: TJ-05, -06, -07. Aerocool has both the Masstige/Coolview and the Spiral Galaxies. Enermax has several: the 10182 and one based on the same design as the Tj-06/Sprial Galaxies plus several server cases you'll never see on Newegg. XClio recently added the 380. Chenming and Antec have some but the designs are getting long in the tooth except for perhaps the P180 - but that has some materials problems. Lian Li has a number of them. Etc...
You can use the Newegg case finder to locate their list, but they define 19" and up as full tower so you'll have to weed the list a bit to get to the real full towers. They cough up 64 models, but many are just color variants. Narrow your list to 3 or 4 and we can nitpick them for you.

Try the "Server" case type there too as it finds some that the "Full Tower" category doesn't. And Newegg's sloppy descriptions let some into the "Full Tower" category that aren't.
These companies have some you don't see on the mass consumer reseller sites like Newegg:
BTOS,
ServerCase,
KeyPower,
Bow Systems. Plenty of options if we only knew what you really need...
YeongYang makes lots of interesting cases, you just need to dig out a place to buy one...
Besides, choosing a case based on height is not thinking too well. If you had defined your needs more thoroughly, I'm sure cases from 19" up could suit - maybe even some mid-tower boxes. Lots of tower cases don't hold a lot of drives if that is really what your need is. The more tightly defined the need, the more accurate our suggestions can be. So don't complain if you don't give us much to work from...
