Okay! So you're looking for a PC that can handle Call of Duty: Warzone in 4k resolution at a 144Hz refresh rate. That's a pretty demanding setup, so we'll need to look for a high-end gaming PC. I'll focus on PCs with powerful graphics cards and processors that can deliver that level of performance.

Okay, I've reviewed the search results. Based on the results, here are a couple of options that look promising for playing Call of Duty: Warzone at 4K 144Hz:

1. Megaport Gaming PC Intel Core i9-14900KF:

2. SYSTEMTREFF High-End Gaming PC Intel Core i9-14900KF:

These PCs are equipped with high-end components that should be capable of delivering a smooth 4K gaming experience at 144Hz, although achieving a consistent 144 FPS in Warzone at 4K will still depend on the specific in-game settings you use.

Would you like me to refine the search with any specific preferences, like a certain brand, memory configuration, or price range?
