Please tell me how much the chassis and CPU cost respectively.

That depends on what chassis and CPU you want.

There are too many such things. There are thousands of CPUs in the chassis. Which one do you want? I don't know. More than 3,000 expensive cases, more than 300 poor cases, more than 0/00 CPU/kloc, more than 9,000 good cases, 600- 1500 poor cases, 200-500.
