For $5,000, might I ask what this collection of parts is for?
Because I see a WHOLE lot of excess in there.
how is this relevant to whether or not a water cooling loop is worth it or not.
It'll be worthwhile if applied correctly.
Before you consider CPU water cooling, consider the fact that most likely air cooling is suffice for daily workflow, a CPU water cooling is mandatory if you run CPU intensive program (keep your CPU at 100% load most of the time) such as Corona Rendering.
Cons : electric bills, so make sure that your works using your PC will be paid off handsomely.
Pros
■ The best buy would be expandable AIO with triple 120mm fans such as EK XLC Predator, Swiftech H220 and Fractal Design Kelvin, Yes they are expensive that's why time you gain for faster completion mean lesser waiting time and more working (or leisure) time.
■ For me working on eyes-pleasing PC somehow keep my creativity mood going, with expandable AIO you can replace fans, tubes and maybe add colors to coolant.
To find out product MTBF you can check from its official website, if the official website doesn't include its MTBF either the product will not broken down of operational cycle or relatively new so I guess they've been using it and will update their result on web page.
