That looks an awful lot like what I have. I’m using the Lian Li PC-D600. I think I’ve managed to get my hands on one of the last ones in the wild. They aren’t even available used on eBay anymore.

What I like most about it (and the Tower 500 that you linked) is that the motherboard is on one side, and the drives are on the other. Keeping the drives cool is easy, I just upgraded the fans on my SATA backplanes and the case, and even under load the drives run very cool.

You can have this case when you pry it from my cold dead fingers.
