I am not sure that you can get the CPU Utilization from the Altiris database, but the rest of the information can be found with this SQL query.

select w.Name as [Computer Name], ip.Device as [Network Device], ip.[IP Address], ld.Name as [Disk Name], ld.[Size (Bytes)]/1073741824 as [Total HD Size (GB)], ld.[Free Space (Bytes)]/1073741824 as [Free Space (GB)] from Wrksta as w

join Inv_AeX_AC_TCPIP as ip on w.Guid = ip._ResourceGuid

join Inv_HW_Logical_Disk as ld on w.Guid = ld._ResourceGuid

where ld.Name = 'C:' and ip.Physical = 1

order by w.Name

 The number 1073741824 is to get from Bytes to Gigabytes.

If you the resource manager on a computer in the database and then choose "View -> Inventory", you can see all kinds of information that the agent has sent back to the database.

If you see a dataclass that is called "HW Computer System". The table in the database would be called "Inv_HW_Computer_System", so it is quite easy to make SQL queries if you can find the information in Resource Manager for an item in the database.
