Can anyone help me calculate the cooling power of 4 327W peltiers in parralell?

First, what TECs. Second what voltage. Otherwise there is no answer to that question.

Regular peltiers, no titans or stacked. at 12v.

Yeah, but that's still not enough information. A TEC can be referred to as a 327w TEC and that would be it's Qmax (maximum energy moved). Or that could be its Pmax (maximum energy consumed). Also each module is different in terms of Dt, efficiency, and Qmax. So I'd need to know the manufacturer and the model.

well presuming that's Qmax at 12 volts and you have 4 of them placed next to each other and you apply 12v to all of them then you'd have 1076watts Qmax and it would draw "S" loads more power than that to power them at that though

Qmax is Q at Vmax, and afaik most modules are 15.4 Vmax. I think I know what you mean, but just sayin'.
With Qmax stated though, I suspect Q12 to be somewhat lower. Haven't played with TEC's for a while though, so I don't really have the graphs in my head anymore and couldn't say what exact Q they'd be running at.

... um... so then

Sorry if this is to hard to understand it's the best way I know how to put it.

I can find the link for the TEC but I was looking for 4 350W TEC's

Example:

4 water cooled TEC's chilling water at 82F could get the water to ___(1)___ degrees.
Then ___(1)___ degrees water could water cool 4 more TEC's to chill another reservoir to ___(2)___ degrees.

___(2)___ degrees water is then pumped to a TEC water block cooling roughly 500W ( 250W {CPU} + 150W {TEC #1} + 100W {TEC #2}).

Can ___(2)___ degrees water cool 500W efficiently. If so how hot will the water be when leaving the water block ___(3)___. And how cold will the water block be with dtmax of TEC#1 (Qmax 150W) and TEC#2 (Qmax 100W) both 68C.

1 = ?
2 = ?
3 = ?

CPU Block = ?

Sorry if this is to hard to understand it's the best way I know how to put it.

I am really tired and have had like 8 hrs sleep past 2 days but hey why not i'll bite.

Very general:

There aren't any commercially availiable TEC's with those specs. If you were looking on ebay stop. I see two otions here. 1. 4x50mmx50mm 31.5v 331w qmax TEC's like mine. 2. 4x62x62mm 26?v (i'd have to look but i'll give ya a link to the store.) 400w qmax TEC's. Either way you are looking at $200-300 in TECs alone. Then you'll need power supplly(ies). That you could search about ebay for or just use 2 24v 1000w meanwells. Add another 200 if your resourceful. So we are at 400 to 500 USD. You can save alot on TECs from china but don't make me go there I guess you are going to stack TEC's in the cpu block since tec 1 and 2 have different Qmax's. Otherwise why? Even if you halve the cost to 250 USD you haven't yet gotten blocks tubing yadda yadda.

I don't know if I would be worrying about the heat just yet unless you have deep pockets. You should also be thinking about what you are going to power this whole set up from. This ain't gonna run on a 20 amp 110v breaker trust me

P.S. I am in no way trying to discourage you lol but i think you are getting ahead of yourself a bit is all.
