Posts magically appeared, so the following is mainly a reply to orek;
Cool the computer properly and the problem will go away with the PSU at the top. How about doing it like my case and segmenting the system so the PSU pulls air from above? Dragging dust from the carpet is a bad idea and running fairly high current DC over a few feet of wire inside the case is an inefficient fire waiting to happen. Plus the poor airflow often causes the heat to build up in the area and get drawn back in. Having that vent in the top of the case is retarded, I can't put stuff on top of it, debris and liquid can fall into it and it makes mounting radiators difficult and otherwise a poor idea anyway because you either cool them with hot air from the system or blow the hot air into the system... Stupid design from all angles. If that vent must be in the top, then flip the PSU over and have it draw air in through that instead of having that long, messy and often hot trunk of wire running ten miles around the inside of the case - where you can't put it anywhere neat because there's no space for it.
@tayyare; Yeah, they're so easy to bend now and it makes me nervous.
@candle_86; No, it actually shortens the life of it for the reasons stated above. Anyway, why then, is the ATX connector still near the top of the board? Should they not move it? At least design the case to turn the board over like SilverStone did, this negated the problem a little but was stupid for completely different reasons.
@MMaximus; Stupid sideways drive bays, hardly any room for wires or the motherboard, no real space for radiators, stupid fan placement, stupid PSU mount... No, horrible case, 3/10 at best. Waste of a good PSU really... Also, is it me, or is are guy's video cards bending? This leads me to another point that is partly the fault of the card makers;
> Long, heavy cards with no retaining slots at the front. In old computers, long cards were common but lighter than today's video cards. A slot at the front of the case (usually on the fan holder) held the cards steady to protect from shock, vibration, thermal movement and bending under their own weight. Now, with BGAs and heavy heatsinks, you'd think something like this would come back, but no. Instead, the drive bays often get in the way.
The last decent cases I saw were the XSPC H1 and H2 (The originals I think, or perhaps the + versions, can't remember and they stopped making them quickly). These got around some of the problems.
