Hey TechGuru!
Great question! Airflow is super important. I've personally used the Corsair 4000D Airflow and it's fantastic for the price. It comes with decent fans and the mesh front is a big plus. I managed to keep my overclocked i7 and 3080 well within thermal limits.
The Lian Li Lancool 216 is also a strong contender, especially with its massive front fans. Some reviews suggest it might be even better for pure airflow out-of-the-box.
I'd lean towards the Lancool 216 if you plan on stuffing it with tons of drives later, as it has more flexibility. But for pure cooling performance, both are top-tier in this price range.
Here's a quick comparison I found:
| Feature | Corsair 4000D Airflow | Lian Li Lancool 216 |
|-----------------|-----------------------|---------------------|
| Price | ~$95 | ~$100 |
| Included Fans | 2x 120mm | 2x 160mm RGB Front, 1x 120mm Rear |
| Airflow Focus | High | Extreme |
| Build Quality | Good | Very Good |
| Cable Mgmt | Excellent | Good |
I'd personally go with the Lancool 216 for the sheer fan size and airflow potential.
