Most full-tower cases are way expensive, so you need to give us a top limit on price. A case like the Thermaltake Eureka or Shark (both basically the same chassis) have good room, are made of aluminum so they aren't too heavy but may seem flimsy at first encounter, and are in the "reasonable" range on price for FT cases. The Eureka (more conservative) version is quite a bit harder to find than the Shark. Last I knew, there were still a few Rocketfish Full Tower cases on fleaBay at around $100. + sh. These were made by Lian Li for Best Buy and since BB couldn't market their way out of a paper bag and had originally overpriced them, they had to blow them out last year at down to $50. each. That is a very large case and also all aluminum except for a few minor parts.
