Is there any reason why I shouldn't use plastic a water bottle as a reservoir for water cooling PC?

[Toxibroke Gaming]

As far as I know we use it to easily refill or clean the cooling loop and add more coolant if needed and make it easier to set up. 

I have a spare high pressure full plastic soda carbonation bottle at home so I hope to use that for filling distilled water.

As long as you are able to put the appropriate fitting holes and seal them up well, it should be fine. The only hesitation I'd have is that the fluid/air in the loop can become pressurized as it shifts between cold and hot temperatures, so these silicone sealers may pop out from the pressure or warp from the cold/hot shifting. I'm not sure if these would actually be considered issues, but those are the only concerns I have.

Leaking, you'd need a pump, you'd need to drill openings exactly to the spec of your fittings, ect. ect. If you want to do a decent job it's a hassle and might not be worth it.

If you somehow manage to properly seal some barb fittings to the water bottle without chances of it leaking and killing your PC, sure go ahead

If you can't properly protect a PC... don't.

 

If you cannot afford proper water cooling, you can't afford your PC to die from your jury rigged crap.

You could just go to Wal-Mart like I did and grab a water container to use.
Mine was one of those that was 2.5 gal capacity and once I had everything setup and sealed I used it for several years - In fact I had made two of them.
I still have one now I use sometimes and it's never leaked (So far) and the big thing is just getting it setup right. The other was destroyed from having to use it for something else and I was rough on it during all that which is why it finally broke. 

I was able to setup the barbs, get it all sealed up and it just worked as you see this one doing with ice in it.
Yes that is the other one and it's probrably 10 years old by now.

As long as the info is accurate and still relevant, the age of it doesn't matter.

That's... impressive.  I gotta stand by my comment tho, as this is a one-off.  But wow.  Strong work.  Glad the reservoir isn't inside the PC at least.

[Toxibroke Gaming]

This was my initial lazy plan. To drill two holes at top, pump outside and just two tubes from top getting in the coolant and out from the bottom. They will be sealed with silicone at the top.

Agreed. Im doing this in an old pc with fx8350 and I'm about to upgrade. But the jury rigged crap is what makes makes it interesting for me. To see how far I can take this DIY setup. 

[Beerzerker]

Unless you're using 1/2 inch tubing, the 8350 will get hot.
I'd also use at least a triple rad (3 120mm fans) to keep it cool. The reason why my res was so big was to have not only capacity but also so it woudn't heat up as quickly, the more water in the system, the longer it takes to get it warm and that was on purpose since I was benching it competitively. In your case all that isn't needed.

As for setting up the barbs/connections one of the things I did was I used some PVC ends/fittings with PVC glue or what's knows as "Blue Glue" made by Oatley - The same exact stuff you would use assembling PVC based plumbing.
Since my res was plastic it adhered and sealed readily to it like it did the PVC stuff itself. You may have a spot or two after assembly it leaks from, additional glue around the fitting/assembly from the inside of the res will take care of that.
Just smear it around the edges of the fitting setup and let it dry, then test again and repeat until it's stops leaking.

BTW I even created a cooling tower a few years ago and did a vid on it. Nothing special, just did it as a project to kill time and see what I could do with what I had to use.

That's so awesome and satisfying to watch. 

And I'm using this to cool my rx480 which doesn't get bottlenecked by fx8350 in assetto corsa and witcher 3 with mods. I'm using 120x240mm radiator for Rx480. Will be over clocking fx as well with really thick 120x360 radiator like you mentioned.

You can also either get a quad rad or have a pair of double rads in line for the same cooling effect. However you want to do it should be OK and I have to say the triple did fairly well for a long time in my case but a quad would have been even better.

If you want to go even further thats up to you such as a quad and a double/triple in line with each other as examples.

Noob question but do I need to add any biocide if it's distilled water loop?

[alyen]

I'm not sure if my idea is any better to get around from using a reservoir container, but my way would be easier if you don't mind buying extra fittings.

 

• Use a 3 way fitting before the in connection to the pump.
• One of the 3 way direction should be going upwards that is connected to tube with a end cap. It's best to make the tube so you can tuck it to the front of the case so its not so visible. Having the tube also makes it easier to refill, but won't be able to hold as liquid as a real reservoir.
• The other 3 way direction is connected to main part of the loop, but in way so the bubbles are more likely to go to the refill tubing. If you have too many bubbles at the start it would likely get recycled through the main loop, but bubbles will eventually flow towards the refill tube. You will need to be able to adjust the pump flow rate to have more control removing the air bubbles.

 

I did tried something like this recently with my current custom loop with a temporary refill tube the utilized the drain valve, but I didn't realize I could have tried to do what I had suggest above at the time. Personally I find not having the reservoir visible looks nicer and gives more space to swap out video cards especially in a tighter case since it was not part of the loop. Next time I change the loop I'm going to do what I had suggested.

You should to avoid any potential problems from that.
There is also things you can get like some of this to drop in the res: https://www.amazon.com/Silver-Coils-Antimicrobial-999-Strip/dp/B00A66HMRC

Those are highly suggested for antimicrobial useage in a system and cheap too. 
Drop it in - Done.

you dont even need a res just use a t fitting

True, but having a res you can access makes it easier to top off the system as needed over time - And it will need to be topped off on occasion.

no the t line is the res but w/e
