Need advice

Hi Friends,
My PSU is dying and I want to replace it. After checking with flipkart and others, I have zeroed in Seasonic Eco 600 watts which I feel is suitable for my needs, only the drawback is the exhaust fan is on top. My present cabinet does not support this. Can you please suggest a suitable cabinet, available in India? The specs are as follows:
MB : G31 Gigabyte
Ram: 3 Gb. DDR2
Graphic Card: Nvidia 8400 GS
HDD: 1 - 500Gb 2 - 1Tb, both Seagate.
Optical Drive: 2 DVD Writers, Sony and Optiarch
Os: Windows 7 Sp. 1
Add. Fans: 1 Rear Exhaust, 1 Front Supply, 1 Side, Supply
I do not play any high end games.
If there is a psu with fan mounted on side which suits my above needs please specify, it would be best. Only thing is it should be available in India.
Thank You.
