Just my 2p on this,
The cpu cooler will be your limiting factor. Most highend air coolers these days are side draft coolers because there is less air resistnace blowing across the heatsink than down it where ultimatly it hits a solid wall. That and heat pipes have mostly fixed the issues with side draft coolers. Its best to have these setup so that they the hot air to the back of the case where it is then sucked out by your rear fans. The only downside is loss of cooling air to the motherboard itself around the cpu.

One thing you can do is make use of spare 5 1/4" drive bays. I did see the other day that mapplins do centrifugal fans which sit in the place of a rom drive. you could use some of these to pull in air at the front of the case and duct it directly into the path of your cpu cooler as height wise they should be fairly close and so the flow should be mostly horizontal.

However i have no experience with these things as im entirely water cooled these days

This is what i saw but as i said i've no experience with them and centrifugual fans can be quite noisey (FX5800 anyone
