1. Buy core spare parts

Although it's generally not a good idea to stash parts, you might consider building a small local inventory of the ones you most frequently replace. Items might include power supplies, hard drives, or RAM for critical servers. If you can get away with it, it might also be handy to have a network switch or module that you've had fail before.

Ans. Based on my part, buying core spare parts is such a good idea for special purposes and it is very useful because it’s one way of upgrading the personal computer and to make the personal computer work faster especially when it comes to networking. It also works less error or error shall we say error free. Although it's generally not a good idea to stash parts, you might consider building a small local inventory of the ones you most frequently replace but, as I was saying, buying core spare parts is very useful to all personal computers because as the word itself “core” it is the central or innermost part of a thing or shall we say it the central or innermost part of the personal computer and it is the most important of anything or the most important part of a personal computer. Buying core spare parts is to refrain from injuring, and treat no error.
