What are the cons to using a PC/cheap PCs as servers vs hardware designed to be used for servers?
I would like to build some my rack servers based on commodity pc components, which would be and cheaper and better performance with same amount of money spent
In face I have already built 2 i7-920 two years ago with stock cooling system. and they all happily running, haven't had single failure and manual force reboot.
Could there be any potential problems?
does commodity pc has higher failure rate than branded server and server components?
