To add: Corsair, Silverstone, CoolerMaster, XClio...
Rosewill, Apevia (formerly Aspire), Q-tech, Powmax, most Ultra, and some Coolmax (though they're getting better) are crap. Coolmax is probably in the mediocre category, but they've been making some solid progress. Rosewill might end up higher, but since you play Russian Roulette with them, it's not worth it.
