The thing about creating your PC is that you decide its design to concentrate on what is vital to add and what not. An off-the-shelf commercial PC is basically a jack of all arts and master of none. System sellers have to strike average that is sufficient for the mythical “average” user.

If one is looking for a compact, quiet PC for your home theater system? There are 3 options. You can use a standard PC irrespective of its size and high noise level or you can a few more dollars for a system from a specialty manufacturer that manufactures according to your requirement or you can make one of your own. Want a system with a ton of redundant HDD storage for editing video or a professional audio workstation? Go for a commercial system that fulfills all your needs, at an affordable price. While building your own PC, you pay only for what is required and rest can be ignored.
