Questions about this item

Can the 64 GB DDR5 memory be upgraded later?

The system has two RAM slots and the maximum supported capacity is 64 GB DDR5, so the current configuration already reaches that limit.

What limits sustained performance of the Intel Core i7-12700T?

The 65 W power supply caps total system draw, so under continuous load the CPU will throttle to stay within that budget.

How loud and hot does the Mini PC get when running all day?

The compact chassis relies on a small internal fan; under constant load the fan speed increases noticeably and the case surface becomes warm to the touch.
