Questions about this item

How loud does the OptiPlex 780 get when the Core 2 Duo E8400 runs at 3.0 GHz all day?

The slim chassis uses a low-profile cooler for the dual-core processor; under sustained load the fan becomes audible but remains within typical office background levels.

What display cable must I already own to connect the Intel GMA 4500 graphics?

The integrated Intel GMA 4500 outputs via VGA and DisplayPort, so a VGA or DisplayPort cable is required for a monitor.

Can I keep my existing DDR3 modules and add them to the 8 GB already installed?

The system uses DDR3 memory; any additional modules must match the DDR3 type and the motherboard's supported speed to function correctly.
