The DCM1100i is designed is specifically to be small and quiet. It
adopts Intel® pBTX motherboard technology to enhance thermal
management, system size and shape, and acoustics. In addition, the
power supply features passive power factor correction (PFC), which
allows the power distribution to operate more efficiently.

Before unpacking your DCM1100i, provide a steady, level, clean
surface located near a wall outlet. The computer should have
enough space around it to allow airflow, especially near the rear
fan. If the system does not have adequate ventilation, internal
components can overheat and be damaged as a result.
Do not damage or destroy the computer box while unpacking.
Rather, save the box in case you need to ship the system in the
future.
Make sure the following components are included in the box and
check to see that they are in good condition. Contact your dealer
immediately if a component is missing or damaged.
•DCM1100i unit
•AC power cord
•CPU heat sink
