Another possible reason for building a custom desktop computer in the future might be to use alternative components in place of those used by PC manufacturers to intentionally hobble their PC's. The fact that computers are becoming more locked down and less general-purpose should not be a secret.

I had 3 personal laptops during my entire lifetime. It is enough:

• one before college
• one during college
• one nearly after college

On the other hand, games are not really possible on them.
