I have a dragon, but it's an outdated case compared to the newer stuff. All the vent holes are 80mm, no dampening for any of the drive mounts, and mine developed a rather annoying buzz from the parts getting loose over time.
If you really need something this huge I guess it's a decent price but if you can live with a mid-tower I'd wait for a hotter deal on a newer design. Of course if you're actually planning on using it as a server case where you can fill up a lot of the bays and you don't care about it rattling like mad or needing a ton of 80mm fans (noisier than using 120's) then it's not a big deal.
The build quality with rounded metal edges is nicely taken care of though, better than in the cheaper new antecs (like the sonata, etc.) but higher end antecs generally have nicer finish and build (P180 or better). If you don't need the huge server size I'd probably wait for a P180/P180b/P182 or something (I paid $100 for mine, a p180b and it was the new version with p182 features), great case and it's significantly better built than my dragon.
This case was great back in the day like everyone mentioned, but in 2009 you can get cases with dampened drive mounting systems, nicer drive rails, quieter fans, dust filters on the intakes, better sound dampening, etc. So it's not really quite as awesome a case anymore-it's not that it's become unusable or crappy, it's just that the playing field got a lot better.
