It can also build a computer from the ground up, to your specifications. It can use parts you bring, or choose from their large selection of new and used parts. In addition to computer repair, EC does work on other electronics, such as televisions and DVD players.

It has recently begun giving computer workshops, specifically for children and families just learning how to use PCs.
