One statement I’ve made over and over in my writings, and every time I speak on the topic of computers, is that there are only 11 major parts in a PC. If you think you can connect just eleven items, then you can build your own.

Recently a gentleman who was interested in building a computer wrote to me. In his letter he said, “I opened up the side of my old machine just to see what it looked like in there. I wanted to get an idea of how complicated it was before I tried building one myself. There were cables going every which way. Are you sure there are only eleven items to connect?”

After a bit of questioning back and forth by email, we determined that my new friend had a very early Pentium that had served him well through the years. In the era of his computer, virtually every port on the back of the case had to connect to the motherboard by means of a ribbon cable. I was building computers back then, and it was a bit like wrestling a squid.

Now, all of those ports are hard-wired to the motherboard, as can be seen in my book “Building a PC for Beginners”. There’s no more trying to plug in everything in a three square inch area. The inside of a computer is much less congested, making the assembly process way simpler than it was.

Another great step to simplify things took place when case and motherboard manufacturers agreed on standardizing screw hole locations. Now you can be sure that the holes for the standoffs that support the motherboard will match with the holes in the case. At one time this wasn’t so.
