proud Lian Li owner here chiming in, the PC-80 is a lovely evolution on the original PC-6 case and PC-7/B/BII. I currently have done many upgrades to my PC-7BII, and it's still rock solid as ever, though the lower drive cage is not the best positioning, you can remove it though.
I'm personally a huge fan of the Silverstone TJ11. There's always the Cooler Master Cosmos II as well. They're both pretty huge cases, especially the Cosmos, but they do look really nice and sleek imo. The Silverstone is a little more geared towards water cooling, and the Cosmos would do great with both air and water cooling.
