Yes, the case is a Lian Li PC-65.
Cooling the 200SBi would be an interesting challenge. The card has chips on
both sides. The business side of the card is hidden in the picture above. Here's an image showing the four chips in a row on the other side. It's the lower of the two cards in the picture.
The four heatsinks you can see came with the card and I am too fearful of damaging the thing to try and remove them to replace them with something more effective! This is one of the reasons I went for the Lian Li case and, also, for the card blower you can glimpse under the card. In my last case I had "card cooler" type fans fitted on an arm over the card. But they run a lot cooler now (at 90MHz at least).
Agree with you about some of the flight characteristics in FCJ but I think Kess (the author) has stated that it's to do with the limitations of the game's implementation of the physics of flight. Doesn't matter too much to me since I'm a very realistic WWI pilot - I'm such a novice I get shot down too soon to worry much about my plane's handling!
One interesting thing is that Red Baron 3D is one of the games I like to play on 3D shutter glasses. This works amazingly well here using Metabyte's eyeScream Voodoo2 glide driver. But I'm unsure why it does since I'm not really too sure that RB3D uses a real Z (depth) buffer. The game is supposed to run at 1024x768 on a
single Voodoo2. This ought to mean that there's no Z buffer. And no Z buffer ought to mean that 3D glasses can't work. But they do to the extent that I get vertigo!!!
Knights Over Europe does look promising. It's amazing that such an excellent PC gaming premise as WWI air combat has created so few real contenders. It's about time there was a breakthrough game to replace RB3D.
