Questions about this item

What interface limits the 128 GB SSD and 1 TB HDD speeds?

The drives connect through the motherboard storage interfaces of the OptiPlex 790, which set the practical throughput ceiling for both the 2.5" 128 GB solid state drive and the 3.5" 1 TB hard disk.

What physical space and power does the Mini Tower case provide for extra drives?

The Mini Tower chassis holds the existing 2.5" SSD and 3.5" HDD, leaving one spare 3.5" bay and one 5.25" bay; the 265 W power supply must cover any added devices.

How is the USB wireless dongle installed, and what step is often missed?

Plug the supplied USB dongle into a free USB port, then install the driver from Windows 10 Pro or the Dell support site; the step often missed is enabling the wireless adapter in Device Manager after the driver loads.
