Why these parts
- At 1440p the GPU dominates, so a mid-range CPU is enough.
- NVMe over SATA — at the same capacity the price is now almost identical.
- Only cases that fit the card length and cooler height are considered.
Best for: For a high-refresh 1440p monitor

| ? | Air cooler height | case clearance is unknown／Check the product dimensions |
| ? | PSU length | PSU length is unknown／Check the product dimensions |
| ? | Memory vs air cooler clearance | No heatsink-height data for the memory／Large air coolers can hit tall memory heatsinks; check the cooler's RAM clearance |
“?” means the data needed for that check is missing. We don't call unknown things fine — check the product page.
