Hello Franck,
I ordered the case on 9/9/2011 at amazon.fr from vendor "RLO France" (their official website is rlo24.com)
The serial is VN10031W2N1107000123
I looked into the "where to buy" part of the thermaltake website , the french website it pointed out to doesn't have anything listed yet, so I need to know where I could get a replacement hose or a replacement LCS, from anywhere in the world, thank you.
In the meantime in order to continue working, I have very slightly elevated the hose with a small rope I attached to the case, so the affected part doesn't touch anything and it gave me room to apply a layer of silicon on the leaking part so it doesn't leak anymore, idk how long this will last but at least I can continue working while looking for proper replacement parts.
