Corsair Obsidian 800D: £225 GBP = ~$350 USD.
I've also had the Xigmatek Elysium (£150), Antec P180 (£110 or so when i bought it IIRC), and numerous other "unbranded" cases. I used the Elysium since i bought it up until a month or 2 ago. I bought it for watercooling, but in the end, it felt cheap and nasty. The wheels broke under the weight of my system, so when i moved back to a single card and air cooling, i switched back to my 800D. It still looks fantastic after all these years, and despite it having poor cooling in general (issue fixed by buying aftermarket coolers for both CPU and GPU), it's a quiet case, it's feet are sturdy, and it'll certainly be the case i use until something more interesting comes along (waiting for some solid pictures of the rumored 900D).
I'd consider the InWin H-Frame mentioned in the OP, but i'm not in the market for a new case right now and it's apparently not good for quietness and the price. Much rather put some of that cash towards a silent PSU and save the rest.
