Hello and my Regards to All Unix Experts

I am a newbie in Unix platform, but using Windows family for more than 10 years. I have a PC with the following specifications, I need to know that can I install FreeBSD 6.1 or 6.2 on that or not. I would appreciate your help.
INTEL Pentium4 D series processor, Gigabyte 945 PL-S series mother board, SATA 250GB Western Digital HDD, NVIDIA NX7300GT video card.

Would anyone please tell me are the specifications are compatible with FreeBSD or not. Besides this I am having lots of problems with downloading FreeBSD 6.2 from web, can anyone tell me some other sites also, and, how to download.

Regards

ATA
