Is this good for 3D rendering?

Yes. The 24-core Ultra 9 285K or i9-14900K plus an RTX 5070 or faster is a strong combination for CPU and GPU renders. Choose the 5080 or 5090 if you render on the GPU most of the time.

How much RAM should I pick?

64 GB covers most editing and mid-size 3D scenes. Go to 128 GB or 192 GB for very large assemblies, heavy simulation or running large AI models locally.

Does it come with a monitor?

No. It is a tower only, with no monitor, keyboard or mouse. Budget for a display and peripherals separately.

Core Ultra 9 285K or Core i9-14900K?

The 285K is newer, runs cooler and adds a stronger NPU for AI tasks. The 14900K is a proven high-core part and can be the better pick if a specific app is tuned for it.

Can I upgrade it later?

Yes. It uses standard desktop parts: DDR5 memory slots, PCIe for a new GPU and room for extra SSD or HDD storage. Check the exact motherboard and power supply in your chosen configuration first.

Is it loud under load?

Liquid cooling keeps the CPU in check, but a 5080 or 5090 under sustained load is audible. Expect noticeable fan noise during long renders, quieter in everyday use.
