PVC Reservoir?

I found this a few days ago http://www.overclockers.com/tips1230/ and decided to pickup a few parts to play with and see if I could eventually use it as originally described or make some changes. The pictures below are simply unglued ideas I would like some feedback on.

First here is what was originally suggested over at Overclockers. Is the “dead space” on the capped end a problem from a circulation standpoint?

This version adds a second elbow (increasing total reservoir volume) and would seem to force the water to circulate more from end-to-end. Would it be helpful bothering to do this in the first place? Does the total volume of water held in the reservoir make a difference to a rigs total capacity to remove heat or have an impact on efficiency? Also does spreading out the in and out barbs help the flow at all? I am not sure if that “dead spot” in the first picture would mean anything.

My last variation here adds a third barb in the middle. Would it make sense to make this either a primary or even a secondary fill port to the system?

I am trying to slowly study all of the components (pump, radiator, reservoir, etc) and figure out how to make a new system later this summer. Speaking of the pump it seems many of the “smaller” GPH pumps have 3/8 fittings by default. Does more GPH necessarily mean a better cooling system or does it come down to how efficiently you match up everything else? I like the idea of the smaller pumps with 3/8 fittings plus I already have a radiator with 3/8 barbs already attached (heater core).

Is there a significant advantage with PVC over conventional PC watercooling materials for res? (plastic/acrylic)
 
No, other than you can't see it and it is more resistant to chemicals.
 
I used to build and use PVC rez all the time, much cheaper (normally free when you dig up parts from construction sites)..........:D
Anyways, you options are basicly limitless and you can built them them to fit your exact needs.

Focus on the later. You are on the right track, get 3/8" a small pump like the DDC 9W or db-1. Assuming that you choose non-restrictive components and your loop functions under normal parameters (ie > 1 GPM) you should be fine, more flow won't necessarily give you better performance.

BTW, those home made PVC reservoirs look pretty nice, a bit big for my tastes, but appealing nonetheless. :)
 
The big plus is that you can make them any size you want, PVC pipes and end caps comes in just about any size you want, just cut and glue together and thread with your thread of choice, thread taps are pretty cheap, no need for a high-end tool to tap threads in PVC, it's pretty darn soft stuff.
 
I think I am going to eventually go with this fourth version:

This makes the overall size a bit smaller and still gives me the third barb at the top as a fill port. The Danger-Den fill cap will probably be a perfect match.
