Cheap Closed Loop?

[Tristerin]

Researched the topic enough that I decided to price out a cheap CLC to make for the experience.  I am kind of dumb founded on how cheap this can be.

 

CPU block - $10-20

240mm Radiator - $10-14

Hoses - $4 for more than enough, a spool in fact lol

Pump with appropriate water movement rate, but potentially suffering dBA levels - $10-20

Fans - Most expensive part of the loop?

 

So I totally understand that you get what you pay for.  But Im trying to figure out on a few of these items:

 

CPU Block - its made of copper, whats the main reason to not go cheap on this?  Smoothness of the mounting surface?  Internals?  

Radiator - Now I see some radiators have more pipes than others etc, but that's pretty cheap.  What makes, say, EKW radiators SO much more expensive?

Pump - Other than noise of the pump (which I would pay for a quieter pump), most reviews are complaining about that, is there a high failure rate untalked about?

Fans - need SP fans but could cheap out for less than $10 so no need to talk about these.

 

*If I do this I plan on not caring about metals mixing and using anti-freeze 50/50, from what I understand now it wont matter*

 

Does anyone have any experience with items like this?  Example links (don't plan on buying these specifically just ones I noticed):

Is it worse than anticipated, bad and ugly at the same time?

Your going to have a mixed metal loop using that rad, you would be much better off with a copper rad and not have to deal with the hassle of galvanic corrosion even with the proper fluids. Main problem will be longevity of the tubing and reliability/performance of the pump with really low grade components.
