yup..and if they wanna save 50% - 100% of the memory prices..
	i wind up going with generics :-)
 	( but its NOT worth it ... and kingston is a good tradeoff
	( for quality/reliability vs price

i wouldn't touch either antec/enermax .. but than again .. i seldom
deal with dead ps ... 
	- for 1Us, its zippy or sparkle and i wouldn't touch any other
	brand(reseller) for 1Us

	- gazillion resellers with their own labels covering the
	zippy or sparkle logos

yup

one has to have as much or MORE air coming in than what goes out
	- need more fans sucking fresh into the case ( harder to do )
	- lessor number of fans sucking air OUT of the case

	- most people have tooo many fans suckng air out of the case
	which causes "thin air" ( vaccuum ) and the itty bitty fans
	won't have any air to bite into 

- if one isn't sure, cover the fan with paper and watch your bios temp
	or disconnect the fan is better

	and light up a cigarette or candle and watch the air flow

	and if one has $$$ .. buy a 3D finite element simulator to model
	all the various heights of parts inside the case


- the p4 cpu temp should be about 35C while doing kernel compiles,
  anything higher means the heatsink/fans/air are NOT doing their job??

fun stuff ... playing with "air"
