Something i couldnt find very easily was how to use the model token like in DS6.9. Alot of different ways using VBS were found however its easy enough to create a token under Settings > Deployment > Tokens.
Heres the SQL Query i'm using:
SELECT DISTINCT [vHWComputerSystem].[Model] FROM [dbo].[vComputer] JOIN [dbo].[vHWComputerSystem]ON [dbo].[vComputer].[Guid] = [dbo].[vHWComputerSystem].[_ResourceGuid] WHERE [dbo].[vComputer].[Guid] = '%COMPUTERID%'
Hope this helps.
