What do you think of my "water cooling" case design?

[Hglazm]

It all depends what you want from a case. I designed this case primarily for liquid cooling. If you want a case that holds many HDD's or multiple optical drives, then this wouldn't be the case for you. However, I could design HDD racks that hold more drives, more tightly packed. Like you say, with the amount of room available, it would probably be possible to hold about twenty.....

Well sure, and it does its job at what you intended it to very well.
I'm just pointing something out. Its not a concern for 99% of people, but I know a couple people that, if this case were on the market, wouldnt buy it because they collect blurays and have like eight kabillion hard drives.

Looking at it, why exactly is there a lower 5.25" rack and then an upper?
Why not replace the lower 5.25" with more HDD racks and leave the upper?
Most people dont use 5.25" reservoirs, and I cant think of any use for more than two 5.25" bays
