workstation contract tracking & budget

Is there currently a feature or trick to track workstation as an asset so that we can track all the contract expiration dates and costs to it as well. Most IT departments purchase desktop/workstations and often times purchase maintenance contracts with each system new. We would like to be able report all workstations going out of maintenance and plan for a refresh.

Also if there will be an option track maintenance cost for contracts by a specific time period (for example yearly, quarterly, monthly)? This would help in reporting overall monthly, quarterly, annual maintenance costs for all contracts and good for budgeting.

Thanks.
