I picked up a Cooler Master Storm Trooper full tower case the other day, I would've loved a Lian Li d8000 but after shipping to Perth, Australia it would be $500-600 which is well out of my budget at the moment, this case was $175 and available locally. It's a bit over the top for an Unraid server but for the price it's got plenty of room, loads of external connections and is very moddable.
it comes with 9 5.25 drive bays top to bottom and includes 2 4-in-3 drive cages. I already had a CM 4-in-3 cage which I transferred across from my old Unraid server giving me 12 drive bays. When it comes time to expand i'll look at replacing them with 5-in-3, there is also an external 2.5" dock which would be suitable for a SSD cache drive and then there is another SSD cage sitting at the bottom of the case which could probably be replaced with another 5-in-3 drive cage as there is lots of space.
Only 2 negatives, the new drive cages have red LEDs and my old one is blue, so it looks a bit odd when they're lit. Also the grommet which surrounds the power supply cable hole is pretty flimsy and came out while I was feeding the power cables through, other than that i'm very happy with it.
