12 Reasons Against
Only Two USB 3.0 (3.1 Gen 1) Type-A Ports
The OptiPlex 3020 is a two USB 3.0 (3.1 Gen 1) Type-A port computer.
Very Slow Processor Clock Speed
The DELL OptiPlex 3020 has one of the slower processor clock speeds (only 2 gigahertz) amongst medium processor core personal computers of this age. The slowest processor clock speed of medium processor core personal computers that are a comparable age to the OptiPlex 3020 is 1GHz, the fastest is 4.1GHz, and the average processor clock speed is 3.1GHz.
If you would prefer a computer with a faster processor clock speed then you might want to look at the HP EliteDesk 800 G1 Mini[plb_2578763_price] (2.2GHz and cheaper), the Zotac ZBOX EI730[plb_2499365_price] (2.7GHz and cheaper), or the DELL OptiPlex 3030[plb_2554127_price] (3GHz and cheaper).
