Note:
-The product is a DIY kit, not assembled.
-The self-made shell must have enough heat dissipation holes. It is best that 50% of the shell area is heat dissipation holes, at least 30%. The life of the machine with good heat dissipation holes can exceed 10 years, and the life of the machine without heat dissipation holes or unreasonable heat dissipation holes may not exceed 1 year.
