Like I said, it's all down to personal preference at the end of the day, each to their own, I just can't stand bare alu internals, I also think that all these high end case manufacturers should start coating the inside of their cases in the factory because it costs a bloody arm and a leg to get it powder coated....
Cylinder reservoirs always look a lot nicer than bay res's imo, but again it's all about personal preference.
I think that you can get cleaner tubing runs with a cylinder res (EK 250 is what I have) than you can with a bay res, though that's just my opinion, there's loads of folk out there that would completely disagree with me regarding this.

One last thing I forgot to say mate, but that Scythe Kaze fan controllers are pap, I've recently replaced my Kaze with a Lamptron FC5 because within the first 2 months of owning the Kaze 3 out of the 4 channels died on me... maybe I was just unlucky with my particular Kaze, but the Lamptron FC5 looks and performs way better than the Kaze ever did.
