Prices are not listed here because it would be too difficult for me to keep up with updating the parts prices with parts located several places in the web site.
You can see all the parts prices in the Parts catalog on the web site.
A pricing guestimate of all the parts listed above is around $550.
This would be a complete chassis, ready to mount in a cabinet.
There are cabinet guys listed on my links page.
