Seagate HardDrive compatible with Dimension 2350

The harddrive on one of our PC’s crashed. It is a Dell Dimension ?2350? – Naturally, Dell wants us to purchase a replacement harddrive from them, but they don’t show any available, and my mgr already bought a Seagate 160GB Harddrive – she was asked some unusual questions when she bought it – so now we’re wondering if it’s compatible…last communication with Dell asked that I call there replacement parts department…I just want to know if the Seagate harddrive that we bought is compatible with the Dimension 2350?

Any one out there have any idea –
