Hardware customer service?

[AMD fan man]

Hello.  My first post, and was hoping members here could shed some light on this please.  I'm new to building and modding, but have always liked to work inside a tower changing/adding hardware for both myself and family members.  Now, I have a Corsair Obsidian 450D, as well as a Cooler Master Master Case Pro 5, which I have since upgraded to the tempered glass side panel.  I also have some CableMod Wide beam LED's, as well as Cooler Master and Thermaltake LED fans.  Looking into the NZXT Kraken X62 and myriad other modding/upgrades from several companies.

 

I said all that because of some of the 1 and 2 star reviews on Amazon, NewEgg, pcpartpicker, etc.  These reviewers mention that there is practically no customer support for hardware that is defective, no replies to support requests, items sold as new arriving clearly opened and used, etc...I ran into that with Amazon myself.  I realize some of the reviews are just BS or someone not really researching what they plan to do, but some are surely valid. Any ideas, stories of good and bad customer service, etc would be greatly appreciated.

 

I was also wondering if Linus would think about adding to his growing empire by talking to the companies he deals with regularly about this topic and possibly being an advocate for his fellow modders and the modding/gaming communities.  I'm very excited by the state of the communities and the invaluable videos, forums, reviews and knowledge we get free of charge to aid in our next build, part, etc.

If you buy from marketplace seller, there's always some risks involved. As for inexisting customer support from manufacturer, I haven't had such. Once or twice with store, but nothing major since we have very good consumer protection in this country.
