If I may, I'd suggest a thread at the top so you can slide the bay res out and fill it from there. Very nice renders though!

the center hole in the rear will serve as a internal fill port. I could also add an extra hole on top. Even with extra holes, could always use threaded plugs.

I'll kick that idea around, thanks!

Definitely a hole on top.

Looks awesome.. Du you plan on making a res with a pump installed inside?

glad you mentioned that, I may be making a double with the pump mounted in the rear of the res. Suppose water into the pump, pumping into res constantly filling res and out some other hole. Not sure yet. See how these non-pump models work out during assembly.
 
Probably use a MCP655 pump
 

clear, i could also do smoke... not sure yet

Looks great!
 
If I may offer a suggestion...  on the 2-bay res, add some slots down each side so it can be slid into "tool free" bays that have the little tabs that stick out to support the devices that are installed.  I've run into issues with several bay devices that don't have the slots and it makes things extremely difficult.
 
Again, looks fantastic!

The tabs are on the sides of the bays, but actually go under the device to hold it up when the tool-free retention system is engaged in the screw holes.
 
Here's a bad pic from the front of my Storm Scout where I have an H50 rad/fan mounted in front.  On the right hand side, next to the fan, you can sort-of see the horizontal tabs laying flat that would be under a single drive/device/res but gets in the way if you were inserting a dual-bay item...
 
 
I can take a better pic when I get home from work.  I currently have the rad/fan removed for mods so the bay area is empty.  I can provide a better shot to explain what I'm talking about.
 
EDIT:  Found this pic online.  You can see how the tabs lay flat and stick into the bays (this shows one tab above a SSD mounting tray in a Storm Scout).  There are tabs like that on each side for every bay slot.
 

The location of the tab is directly under anything you put into a single bay.  It's a support tab... so if you put a DVD drive in one bay, it would actually sit/rest right on top of the tab.  Take the height of your single bay res, subtract it from the top of your dual bay res, and there's the horizontal measurement for the slot.  Add 1/16th of an inch to each side for a 1/8th inch total gap and you'll be all set.  As for the width of the tab, I'd guesstimate it at no more than 1/4 inch.

here is how I modified the design to include the notch from the sides. Its roughly 1/2 the distance in depth of the overall thickness, not to compromise the side wall.
 

what would you guys think that if it wasn't affixed to the front with adheasive, instead having a screw protruding out the front, like the lamptron fan controllers...
 

I made the plate the size of the front bezel of a dvd drive for the single bay one.
 
I struck out at a local supply, I will have to order my acrylic. Oh well, few days won't hurt. I may have some aluminum around to use to make a bezel for the prototype. 

well, its gonna cost me about 100 bucks to get the supplies to make these res's. That's due to the cost of the materials themselves and the solvent that basically weld's acrylic together, as well as the tap and drill for the pipe thread for the g 1/4 spec.
 
gotta sweet talk the wife in letting me get this stuff :-)
