For editing video you mainly just want a massive graphics card. Those do most of the processing.
In terms of desktop graphics, you're gonna want in ATI cards, a 4850 or higher. With a Nvidia, a 9800GT or higher end card would work well. Those are the newest and best priced cards, but a Nvidia geforce 260 might work- but I'm not too informed about the newer numbers in the Nvidia line, and I find them to be confusing since they're so different.
Quad core isn't required, but if you're going to beef up the GPU, you might as well get a quad core- I like my Q6600 quad core processor and its worked excellent for me.
For memory, I highly recommend getting DDR3, especially in a desktop, since it should be down to a reasonable price now(Been a year and a half since I built mine, and I settled on DDR2 800).
Blu-ray? Not necessary, but if you have a 1080i or 1080p TV, you might want to look into it. If you don't have a fancy TV, its probably not going to matter.
Hard drive should just be 500GB or larger. Preferably larger, since HD videos take up a lot of space.
