that the armor LCS?
its certainly a nice case, managed to have a look at mine before i went on holiday, its 3/8" tubing, and the stock pump is a bit weak, so i bought a new pump and res to use with the 'built-in' rad.
it looks very nice, but i wouldn't use it to cool a quad core and a GPU myself, the pump and tubing combined means it just wont cool them well, especially so if over-clocking.
afaik you *can* even remove/replace the rad with on of your own choice, meaing you can replace all the stock water cooling with something more substantial ie 1/2" tubing.
i had a look at whether you could replace the stock water cooling's barbs and it didn't look like this would be possible, i didnt try to hard as i didnt want to break anything, so i'm not to sure
you could probably do a CPU+ northbridge on the stock...
there is plenty of tubing, even adding the extra i needed between the pump and res (the stock pump/res is connected) i still had over 30cm left so plenty of room for error.
thats about it really, its a very nice case for what you pay, and the water cooling block looks good (will get to test it next week)
