Well a $9 shipping put's a stake in this for me, while the 2-80mm fan are fine but they don't appear to be "smart" so both run at a given speed at all times.
A bunch a Egg'ers love it but some Web reviews are lukewarm on this, one of their more basic offerings.

Sorry, I must retract the Fans are thermally controlled, I had to work my way to the charts on the Thermaltake page to really find that they're advertising that feature. Hardwaresecrets picked-up on one thing they use 20AWG wire for the main 20+4 loom and the sleeving is weakly done. But it has some. So if it wasn't for shipping & tax (in my case) it would be a decent deal.

I have one powering a C2D 2.4, 4GB, 4x 320GB, Radeon x1600, RAID card, DVD-RW, etc, and it has remained stable in 24x7 operation for about 8 months now. I have another one in a smaller PC and it has run fine for a similar period of time.
