Questions about this item

Will the Intel Core i7-14700 throttle under sustained heavy workloads?

The processor has a 2.10 GHz base frequency and can reach 5.40 GHz turbo, with a 33 MB L3 cache and air cooling in the SFF chassis.

How loud or hot does the SFF chassis get when running all day?

Air cooling handles the 20-core CPU in the compact 10.6 x 3.7 x 12.1 in case; expect typical business-desktop fan noise and warm exhaust under continuous load.

Do I need to buy a monitor cable to use the dual 4K display support?

The rear panel provides one HDMI 1.4 and one DisplayPort; you will need compatible cables for each monitor you connect.
