Questions about this item

How loud or hot does the OptiPlex 7770 get when the i5-9500 runs at 4.40 GHz all day?

The 9th Gen Intel Hexa-Core i5-9500 operates at a 3.0 GHz base frequency with a 4.40 GHz turbo boost; thermal output scales with sustained load on the integrated Intel UHD Graphics 630 and the 2.5" 1TB SSD.

Which peripherals must I already own to use the USB Type-C gen2 and DisplayPort outputs on this all-in-one?

The system includes a USB keyboard and mouse; you only need a monitor or dock that accepts DisplayPort or USB Type-C gen2 for extra screen space.

Will my existing DDR4 SODIMM modules fit the 204-pin slots if I want more than the 8 GB installed?

Yes, the board uses 204-pin DDR4 SODIMM slots supporting up to 64 GB total, so compatible DDR4 sticks can be added alongside the factory 8 GB.
