Comparison Summary

Which One Should You Choose?

• For maximum expandability: Choose the DS3H V2 (4 RAM slots, extra PCIe)

• For smallest mATX build: The K V2 saves space while keeping most features

• For tiny builds with Wi-Fi: Only the A520I AC offers wireless in ITX form

• Best value: The K V2 offers the lowest price for basic needs

Note: All A520 models have PCIe 3.0 (not 4.0) and lack overclocking support. They’re best paired with Ryzen 3 or 5 processors for budget builds.
