Computers and Computer Hardware
- Dell Go to www.computers.harvard.edu, and select Dell departmental purchase. You will have to register; use your fas.harvard.edu email. Configure your computer (you can get any system, or a "Harvard standard" system). When checking out you will have to select a shipping address - be careful, if you select "17 Oxford St" from the dropdown list it will probably have somebody else's name attached to it. If this is your first time ordering this way, you will have to manually enter the address with your name as the recipient. For future purchases, find the "17 Oxford St" entry with your name as the recipient. The same warning applies for the payment address; be sure to select the "Jefferson Business Ofc" or something like that; if you select other addresses with "Jefferson" in the name it will go to somebody else (for example a secretary in the HETG).
