I'm sure the thing weighs a ton, being steel. And that's without fluid, lol. The pumps in those were pretty...well....not to be mean, but-- ass. 1/4" tubing. Aluminum rad with 80's cooling it (I think two blowing downward, 1 blowing upwards(?) or the other way around). I guess it just depends on what kind of hardware you want to cool with it, and what your expectations are, I suppose.
Personally, I'd just get a good heatsink/fan with the $35, lol.
That looks a lot like the Alienware Predator 1.0 case, sans plastic covers. I always thought the Predator 1.5 case was much better in terms of getting cool air into the bottom and hot air out the top.
