HELP!!!! PLEASE, I NEED HELP UPGRADING MY VIDEO CARD ON MY HP SLIMLINE S3620F!!!?

I just bought my HP Slimline s3620f, it has a 128 MB graphic card, I want to know how can I upgrade it, I want a better graphic card, but it's difficult to find it, because it uses a special mini video card, I called HP and they say they don't sell it, they told me to go to nvidia.com and I can't find it, I also want to know if I have to change the power supply too, and where can I find it??? Please someone who knows this stuff, I really need help, I was thinking about selling it on eBay, to buy a normal desktop, because it's difficult to find this video cards, and parts for this computer. Thank you!!!!!!HELP!!!! PLEASE, I NEED HELP UPGRADING MY VIDEO CARD ON MY HP SLIMLINE S3620F!!!?
It's got a 160W power supply. Yikes.

And it's one of those weird, long version flex ATX12V power supplies,

On the other hand, a 9600GT card should run quite well, with a E5200 Wolfdale (Core 2 Duo @ 2.5 GHz).



I don't know anybody who has done this upgrade, so you would have to try it, then report back, but I've only come across a couple power supplies that look like they would be good for upgrading one of the HP Slimlines.



Shuttle SilentX PC50 300W (21.5A total on the +12V),

Yeah, you need a slim-line PCI-e card. The best you'll get is a 9600GT, and Newegg carries it. Also, I think you only have a 180 watt power supply, so upgrade that for sure. Buy the best Seasonic you can if it's mATX, and if ATX look at things like OCZ StealthXStream, Earthwatts and PCP%26amp;C- all usually heavily discounted at Newegg. You may need extra cooling, too- if the card gets hot, dremel a cut out in the rear of the case and add a fan! Seriously.

That's the elusive card.
