He said that a card without a cooling fan is going to heat up more. And that is pretty much the case....however it won't be heating up to the point that it kills itself or your machine. None of these cards will be suitable for any advanced gaming. And within your price range, I cannot find a card with a fan that is less than $40.
The lowest priced PCI card, supporting DX9, with 512MB RAM with a cooling fan is the $80 one

Even if you could find a powerful PCI card, it won't be $20-$40 and it will draw more power than your power supply in your computer will generate. I think the Dimension 3000 had a simple 200 watt power supply if I remember correctly.
Remember, there is always eBay where you can probably find a deal. However, I cannot sort quickly in eBay like I can on NewEgg..so I'm not going to scour eBay looking for a card with the specs that you need. I'll leave that up to you.
For aero you need at least 128MB of RAM, support DirectX 9 class graphics processor that supports a Windows Display Driver Model Driver, Pixel Shader 2.0 in hardware, and 32 bits per pixel.
