depending on your budget for a new case, you could do much better than the TT Armor.
the CM690II (regular) is like $85 and is a decent case for water cooling, but a little tight. As you increase your budget, you can find awesome cases, like the Silverstone TJ07 for $350.
The HAF-932 is decent, depending if you like that type of style. another case i'd reccomend is the Cosmos S. keep an eye on the For Sale section to find a good deal (even better if it's local), you can save some money and probably find a case above your budget for a decent price.
keep in mind, some case manufacturers simply use better design/structure and materials for their case, which is reflected in their prices. For example, Cooler Master has some decent cases, but consider the amount of tacky plastic they use, when compared to Silverstone or Lian Li's, who tend to use minimal plastic, and have nicer designs.
