Hi. I'll shortly be switching platforms from PC to Mac and i'm considering a PowerMac. However, having come from the modding section of the PC community, i'm aware of how much dust and grime gets sucked in through the front intakes - even with a high-end case. Keeping on top of it can be difficult and it really undermines aesthetics. I just wondered - is this a problem with the G5 PowerMacs? When I first looked at one in the shop, I couldn't see any filter inside the front facia, which surprised me. I'm sure the large fan cuts some of this problem out, due to the slower speed, but I imagine that it's still an issue. Would anyone be so kind as to clarify this and also tell me how easy the PowerMacs are to clean internally? Cheers.
