Body (FB-friendly version):
Here are the three mistakes we see most often:

Choosing based on lowest individual prices.

One cheap product can make the total package look cheaper, but it often leads to later upgrades.

Assuming top specs are always necessary.

Over-specifying drives up cost and creates waste for items that don’t need it.

Mixing components without experience.

Uncoordinated products can cause hidden costs to make the system work properly.

A smart one-stop setup avoids all of these:
Balanced specs, right for real use, and total cost optimized.
