bottom mounted power supplies
"Ian D" wrote in message ... The PSU is usually in its own compartment, basically sealed off from the rest of the case, except for cable routing openings. Also, there is a fan, and probably a drive bay for 2 HDs, all in line with the PSU. There's a straight line front to back air flow. Antec does indeed make cases where the power supply is in a separate compartment but these are not the norm and may be more expensive than what the original poster wants to spend. http://www.newegg.com/Product/Produc...82E16811129061 The original poster is looking at the 300 series cases which are more affordable but do no feature a separate compartment for the PS or behind the motherboard wiring. The 300s are still a good buy though. -- -smithdoerr |

bottom mounted power supplies
"coltrane" wrote in message
... I'm sure I read somewhere (possibly in this newsgroup ages back) about the problem of dust with bottom mounted power supplies. Yes, it was in this newsgroup: http://alt.newsgroups.archived.at/co...314126512.html - looking back the consensus seemed to be that dust would be unlikley to be a problem (YMMV). While looking for this I have read comments elsewhere which implied that dust could be a problem, but none which indicated it IS a problem. The case I am looking at says it has filters to prevent dust. This doesn't apply to the PSU so dust might be an issue especially being on bottom. I suppose that since the PSU sucks air out of the case, having filters on the main points of entry should help. If you end up buying it then don't forget to periodically look at your filters to clean them. I had a bit of a shock over the weekend at how much dust was in one of my filters on my pc. Given that hot air rises you do have the advantage with a bottom mounted supply that the power supply should run cooler. On the other hand this would imply that other components might run hotter - so you then need a fan at the top of the case to get rid of the hot air - which I assume would be provided. The case does have 2 fans on the top. Sounds reqsonable. -- Brian Cryer http://www.cryer.co.uk/brian |

Hot air does rise, in the absence of other air movement, but what happens when there are multiple fans interrupting it, directing it along pre-defined pathways? Jon |

I would suggest you add a 120mm fan to the front.This would keep your HD
cooler The top 2 fans draw the hot air from the CPU cooler out. The bottom mounted PSU will draw fresh air in if you buy the right model and the PSU Fan will blow that cool air over the inside of the PSU and out the back of the PSU Theoretically none of the hot PSU air should enter the case. After looking at this Article you might want to reconsider that purchase but then it all depends upon what your putting inside http://www.anandtech.com/show/3439 You might want to consider the 600 for only $20.00 more peter If you find a posting or message from me offensive,inappropriate or disruptive,please ignore it. If you dont know how to ignore a posting complain to me and I will be only too happy to demonstrate :-) "coltrane" wrote in message ...

Even with top mounted PSUs, I always try to keep PCs off the floor to
reduce dust build-up. Even 2cms above the floor reduces dust significantly. If you have to put your PC on the floor, put it on an old phone book to get it up a bit. good idea. gives me a reason to go cut up some 2x4s sitting in the garage |
