Questions about this item

Does the Corsair 4000D case include a monitor, keyboard or mouse?

No. The PC ships with the tower, internal components, Windows 11 Pro and a power cable only. Peripherals and a display must be purchased separately.

Should I pick the 128 GB DDR5 configuration or add more memory later?

Four slots are populated for 128 GB DDR5. The board supports up to 192 GB, so you can add modules later if workloads demand it.

What does the 20-core Ultra 7 265K at 3.7 GHz deliver in daily rendering work?

The 20-core CPU boosts to 5.50 GHz with 30 MB L3 cache, cutting multi-threaded compile and render times versus lower-core chips.
