My recommendation is to touch & check out the Tsunami in person before you pull the trigger & buy. Like you, I thought it looked good on Web sites when it came out. Then I was at Fry's one day and cruised thru their case row. They had a Tsunami on display so I checked it out. Very disappointing. The front door looks like two pieces, but it's actually just one and it feels cheap. I'm almost certain it's plastic (unlike the CM WaveMaster, which is rock-solid anodized aluminum and the case that Thermaltake ripped off for its Tsunami design). And when you open that front door, what's behind it is pretty bland, both in look and construction.
OTOH, the Tsunami has (I think) 120mm fans, so that's a plus.
In the interest of full disclosure, I'm admittedly biased against Thermaltake anyway 'cuz I think they're dishonest and don't deserve a dime of our money. IMHO, they blatantly lie about their fans' performance, which should be unacceptable.
But hey, to each his own. If you really like the case, what I think is irrelevant. I'm sure you'll get plenty of glowing endorsements from Tsunami owners.
