That is interesting Yewen. I read one account on an Asian site of resonating side panels. That worries me a bit. Have you got any links you can post ?
Also, even with the size of the TJ09, Clone had to remove the back support brackets to get the Tuniq in. Plus you need to add additional top fans and hard drive fans youself. It also looks like the fan for cooling the gpu area is difficult to remove. I also don't like the window on the TJ09. Windows tend to scratch easy and show up swirl lines under light even after using a microfiber cloth. More and more now I am leaning toward the Lian Li. I also like the fact it can take 2 psu's, so when I eventually go sli, I can get another Seasonic M12 which with modular cabling are easy to keep tidy.
I am convinced the top fans won't get in the way of the Tuniq due to where my cpu socket is positioned. My only potential issue now with the Lian Li is whether the mobo tray will slide into place with the Tuniq installed. EffBee says it does not which is a bummer.
