Questions about this item

Will the 16GB DDR3 memory need to be replaced and what is the maximum this desktop supports?

The system ships with a single 16GB DDR3 module in one of two slots and supports up to 64GB total, so you can add another stick or replace both later if workloads demand more capacity.

What component hits its limit first when the Core i7-10700 runs sustained heavy workloads?

The 64GB memory ceiling and the two-slot board are the first hard limits; the processor itself will throttle only after the cooling solution reaches its thermal capacity.

How loud and hot does the 3090 get when it runs all day with both drives active?

The compact chassis and stock cooler keep the i7-10700 at normal office noise levels, while the SATA SSD and HDD add negligible heat during continuous operation.
