With a little research, you can find affordable GPUs that will transform emulator performance and graphical capabilities. Just know the limitations and restrictions of your particular Optiplex model.

Storage – SSD Boot Drive + HDD for Games

A significant way to massively speed up overall system performance is swapping the main drive for a fast SSD boot volume. This tremendously reduces loading times for both Windows and loading emulator states.

  • Clone existing HDD over to a 250GB+ SATA SSD using free software tools before swapping it in.
  • Alternately do a fresh Windows 10 or Linux distro install to clean bloat. Some Optiplex have recovery partitions.
  • Add a large secondary HDD like 2TB+ for mass game ROM storage. Prices are low for high capacities.

Combined with the SSD providing a snappy boot volume, high capacity magnetic storage offers essentially unlimited room for housing every game ROM you could want.

Steps for Adding More Optiplex Storage:

  • Ensure SSD is compatible with SATA ports – some Optiplex used proprietary SSDs so research first.
  • Initialize and format drives once connected through OS disk utility before transferring data.
  • Secondary HDD can connect via open SATA ports, but external USB 3.0 works too.
  • Migrate existing files or clean install OS and programs to SSD before wiping old system drive.
  • Large external USB hard drives provide flexible storage if internal bays are limited.

With your core OS and programs on the SSD, and game libraries stored on the sprawling HDD, you’ll have an optimal storage configuration.
