PSU Fan Direction and Power

I have 2 questions:

1. I have Be-Quiet-Pure-Power-L8-CM 430w and a cooltek cuble

. Now the PSU sucks in air so which direction should I have the fan facing? For airflow, which direction is better, owards the case mesh or towards the motherboard?

2. I will only have 2 hdds in this case and was wondering if I can get one molex cable to sata x2 http://www.ebay.co.uk/itm/Molex-to-...itter-Cable-/251169263950?hash=item3a7adad14e to power the 2 hdds, will be safe or should I get individial wires for the hdds? I want those cables because of cable management.

Motherboard is Asus Maximus VI Impact
 
I just love those cases but as you say, the biggest drawback is cable management.

Let's get the psu orientation out of the way first. You could use it either way but the best way for airflow would be to have the fan sucking air in from outside the case so it would be up against the mesh side panel. That way the cpu cooler won't be fighting with it for airflow. The drawback is that without a dust filter the psu will be sucking in dust. Dust filters are cheap enough though and a magnetic one (some come with a magnetic adhesive strip that you stick to the case and then stick the magnetic dust filter to that) would do the job well.

That power cable should do the job but it is just too cheap for me. Cheap means cutbacks on quality and it could be using thinner than normal gauge wires. If you do buy from the bay I would buy from a seller who states what gauge wires they use.
 
The Demciflex ones are very good and they come with the adhesive magnetic outline that you then stick the magnetic filter too if you are using it on aluminium or plastic panels. If it's a steel panel then stick the filter directly to it.

Silverstone also does magnetic dust filters and some even come in white but I don't think that they come with the self adhesive outline so you would have to stick the filter directly onto the psu.
 
That look's like plastic mesh similar to what I had on the bottom of my old Coolermaster Scout case for the psu intake. No it doesn't work. Not completely anyway as it stops hair etc but still lets dust in. Just buy a proper dust filter. It's worth it in the long run.
 
If you have the psu fan facing the cpu then you will probably see higher cpu temps as the psu will be taking the air that the cpu fan would otherwise have had. It's going to be hot in that case as it is without taking cooling away from the cpu.
