Just for discussion, show n tell? 
I bought a Thermaltake Core X71 extra large tower case a couple of years ago. Best case I've seen for ventilation/cooling with a decent price point of 150 USD, although I paid alot less for mine on sale.
Highly configurable internals, all removeable, with the only plastic being the sliding HDD drawers. All steel construction, inside and out.
It has 4 side removeable side panels with one being a smoky tempered glass, and the front panel removes as well, covering space for 3 large intake fans.
The top panel and front panel both have thinline filters, and micro screens, the smaller lower side panels have micro screens to reduce dust intake as well.
The filter screens are washable.
Top case wall can accept triple fan water cooling mounts, the rear wall has room for only one large output fan.
The interior mounts are somewhat configurable, holding any size motherboard, 4 internal HDD, and up to 5 Internal SSD drives.
Space for a 2 DVD drives and overall huge amounts of air circulation space, with the power supply held in the lower 7 inch tall component compartment.
The power supply compartment is huge, and will accept cooling fans as well.
