Before i spend a lot of money, will I be able to fit a Gigabyte Radeon X800XL with the Silent Heat Pipe into a 330P

And if it does fit will i still have access to the pci slot? If not does the stock cooler on the x800XL allow you to use the PCI slot.

Looking at the images ive seen the side that will be next to the pci slot looks very compact so it might well fit:

However the top of the card is quite chunky so im thinking i may not be able to close the case

As another question, where can i purchase a wireless card to fit inside the little secret expansion slot in the bottom of the machine?

Thanks in advance to anyone who takes the time to answer. This will be my first venture into SSF pc's so any advice is greatfully recieved.
