So this can be done:

+--------------------------+-----+---------+
| Item                     | Qty |   Price |
+--------------------------+-----+---------+
| SUPERMICRO MBD-X9SCM-F-O |   1 | $168.99 |
| Intel Core i3-2100       |   1 |  $99.99 |
| Syba SD-CF-IDE-DI        |   2 |   $7.89 |
+--------------------------+-----+---------+
|                         Total: | $284.76 |
+--------------------------+-----+---------+
