I like the LEXA a lot. I own a NZXT Apollo and it's great and quiet, yet still cools pretty good. I can vouch for their quality cause it's perfect. It's all screwless except the side panel, and it also survived a 3 foot drop onto rocky asphalt.
I also like the Ttake but those wings on the front are the STUPIDEST thing ever. They serve no purpose and look dumb. That's just my opinion.
Yeah the Lexa should be pretty good, I know that it has fans (or blowholes where you can mount fans) on the top and bottom of the case, which is really nice, but IIRC they are only 80mm and really 120mm is ideal nowadays. I have 3 120mm fans in my case, front, side, and back. They are quiet, but they keep things cool too so it's all good. I can assure you the case will be quality, you should post pics and a review or something when you get it running.
True, but I think there are better cases out there with about the same cooling capability and features. Aerocool has been doing the ludicrous mm fan thing for a long while now and their new cases are HOT! And I mean that in a Paris Hilton way.
The thing is though, you can replace 80's and 120's with super-high CFM Silverstones and probably cool way better than the 20-something cm fan (a little hard to find 25cm fans btw, lol). But then again it will be louder than you can believe.
