I'm able to get these information:
?"HOST name = "@HOSTNAME
?"IP address = "@IPADDRESS0
?"OS = "@PRODUCTTYPE
?"ver = "@DOS"." @BUILD
?"SP = "@CSD
?"Memory = "MemorySize(0)" MB"

...but still i could use some help finding out NT4 servers serial no., manufacturer (IBM, Dell, HP), model number and the amount of CPU's. I don't want to install any software or addons to them because they are production servers.
