Water Cooling 104 - Reservoirs

Fourth in a series of water cooling threads spurred by the recent uptick in questions on the topic..... see starter thread here:

Water Cooling 101 - Should I or Why Bother ?

This thread is obviously intended to focus on Reservoirs. Again, the THG Water Cooling Sticky is a great place to start.

This thread is intended as a spot to share ideas on the subject of Reservoirs and Fans. As indicated in previous threads, the sticky is a bit outta date as one of the main resources (skinneelabs.com) is now gone. There is still load of information to be found on http://martinsliquidlab.org/

In looking at reservoirs, I was originally set on a bay type as it seems the most convenient. As research continued, found numerous instances of failed acrylic reservoirs where the glue had given up and the owner experienced severe leaks. As acrylic is susceptible to deterioration from both heat and UV, I started leaning more towards interior reservoirs ..... but most of those are also made of acrylic.

At this point leaning towards the AquaComputer Aqualis XT Scratch Resistance Reservoir w/ Fill Level Sensor and LED Holder, w/ Nano Coating. It's a bit pricey but made of 5mm thick borosilicate glass tube, has built in pressure equalizer

It is a bit "cheap" on ports with only 3. I was planning on IN-OUT-FILL-DRAIN ports but this unit comes up short in this department. It would seem that I'll have to double up on the fill / drain port or just unscrew the pressure equalizer to fill.

Alternate ideas, suggestions nor comments ?

Nice video review by Singularity here:

I wouldn't worry about Acrylic unless your running Ethylene Glycol or some other Alcohol in your loop. Their will always be horror stories of any product.
Though if you had a screw-assembled tube reservoir there would be no need for glue at all. Its only square reservoirs that would need glue to keep together.

Pretty sure there is an AquaComputer reservoir thats made of metal and glass, looks like something you would pull out of a car engine. I'l see if I can find it.
Ahh, this. Pretty sure you can get them in metal, but it could only be an aesthetic difference.

Need more ports?
Their called T-Fittings and G1/4" Male-Male adapters :p
 
Oh I know all about fittings :)

G1/4" x 3/8" ID Rotary Comp. Fittings - $13.99 ea
G1/4" x 3/8" ID 90° Rotary Comp. Fittings - $18.99
G1/4" x 3/8" ID 45° Rotary Comp. Fittings - $15.95
G1/4" tee - $13.99
Quick-Disconnect for Drain - $19.95
Male Coupling $5.25

I actually have a CAD schematic using them (I know, anal engineer)...... lets see if I can go line art:

| Fill port
|
|~~~ ~~~~
|
|
|
|
|___ Reservoir -> To Pump (return line not shown but all 3 at bottom on Aqualis)
| Tee
|
|___ Quik-Disconnect for drain line

So if the squiggly lines are the water level in both the fill line and reservoir when pump off, I wondered about any negative effects of the air trapped in that line
