Looking For Cases Similar to CM Elite 360/361

I’m looking for a compact chassis capable of utilizing a full ATX motherboard that isn’t a cube! I’d like something that can be setup horizontally or vertically.

The dimensions on the Cooler Master Elite 360 & 361 are great, but they are either discontinued or very hard to find. They also have outdated front panel connectors, so I’d like something more up to date.

I’m aware of the Thermaltake Core G3, but despite supporting ATX motherboards, it only has 2 expansion slots (what’s the point of ATX?).
