Form factor and equipment
Check whether the listing is a tower, compact PC or all-in-one, and whether a screen and peripherals are included. Compare dimensions with the available workspace.
Performance and connections
Look at the processor, graphics, memory and required display connections together. Original reviews can add context about performance, noise and cooling.
Configuration and upgrades
Confirm the complete model code, operating system and storage. Check supported upgrades and physical expansion space rather than assuming that every component can be replaced.
Reviews, prices and model codes
Read the original expert reviews for the tested model and use the COR Score as a summary of included ratings. Compare the exact edition, package, delivery and current availability when checking retailer offers.
