I'm not disputing that prices have gone way down, or that processing power is greatly advanced for homebrew computers. However, it's my observation that homebrews are the minority of deployed desktops, just as desktops are declining in numbers.

It's also a generational observation, having come from the days of Z80's and later the ISA slot based PC/AT motherboards of IBM. When the ATX standard was adopted, with more of the i/o controllers being built in as part of the BIOS, I found that "plug & play" initially was better termed plug & pay for upgrades in hardware and software. Numerous fiascos with HP printers, Twain devices, and the like must seem like distant memories.

I'm glad that modern BIOS and component designs are making it easier, but I do see the days of the homebrew PC coming to an end.
