old school is always the best unless someone wants to show me something better that was invented otuside the realm of bling.
Today's world your Custom LCS isnt special unless it has colored coolant running full rigid tubing illuminated til no tomorrow from the gazillion leds you have inside your case.

Seriously, its all about what metals your using.
I still use silver.
Silver was shun'd because vendors didnt want to cough up more expense on thicker and better nickle plating with more chromium in the alloy.
They also want you to use there premix because they make the most profit margins off dye + antifreeze + distilled water.
Lastly, unless your running thermaltake, or running eK alu budget series, you really dont need to worry about corrosion with copper + brass.
I run silver, and i can care less what vendors say, i know what im doing and have been doing it since 2006, which predates before even some of them existed.
