Help me with an airflow problem

[almoststew1990]

I have the following gear in a naff cheapo case:

Sandy Pentium G870 3.1GHz CPU (@60c under load) on a 92mm Aidios cooler
2x2GB RAM
1x SSD
1x 3.5" HDD in same shelf (out of the way)
GTX 580 (@90c after 15 minutes of gaming)

As I've cleaned out the GPU and the CPU has recently been mounted and remounted, I think the problem is the lack of air and crap circulation in the case:

I think the CPU is warm as it is pulling the PSU air over it?
I think the GPU is warm because the inhale fan can't move enough air and is generally suffocating?

As the mobo is ITX it seems I can't mount the CPU cooler sideways.

How would you do the airflow in here? The GTX is a Frozr II cooler so not a blower designed one.

Doh! I didn't know PSUs inhaled fro nthe case! I thought it was the other way around

Edit- Is it better to push air or pull air?

this is a second PC that I mess around with and use for games in the Bedroom, so I'm hoping to not spend more money on it (other than a quad core to let the GTX 580 loose).

Even with the side panel off, I still get 77c on the 580; were they just hot cards?

If cases are really that cheap I might get one for £25 or so, but it would have to be MATX.

What MATX case would you recommend at the cheapo end of the scale?
