What hard drive size should I need for UNIX?

Hi Folks:
   We intend to buy a workstation. Due to our tight budget, we have to consider
cost-performance (or cost-effect). The major factor bothers us is what size
of hard drive should we need. So I would like to ask:

1. How many MBytes needed for UNIX system / developer?
2. How many Mbytes needed for TCP/IP system / developer?
3. How many MBytes needed for NFS system / developer?
4. How many Mbytes needed for X window system / developer?
5. How many Mbytes needed for C compiler / developer?

Any answers appreciated.
