I use old discarded computers for Linux and upgrade them to the maximum that my spare parts allows me to and for my computer use it's all I need.
I can afford to buy a System 76 computer if I wanted to spend that amount of money however why should I if what I have cuts the mustard for what I need.
I believe that computer parts have become outrageously overpriced along with everything else in the consumer industry.
It's my choice if I choose to buy or if I choose not to buy outrageously overpriced consumer products and nobody is forcing me or anyone else to do so.
As long as Linux works on my outdated Frankenstein boxes I'll keep on using them gives me something to do in my old age and plenty of parts that can be purchased from Ebay cheap.
And besides I'm a cheap old bastard.
Cheers.
