Our Mission

We are a privately owned computer sales and repair store located in Lombard, IL (20 minutes outside of Chicago). We are here to please the customer and make the extra effort to insure the customer is satisfied with any orders placed with us or computers repaired by us.

Company Profile

We excel at offering our customers great products at great prices. We are a proud member of the Dell Channel Partner program.  We also offer great deals on all other brands of computers, as well as white boxes custom built to your specifications if that is your preference.  We maintain a high level of stock on most PC, networking components, printers, and peripherals. We use local suppliers on most of our parts so if we don't have a particular item in stock, we can order it, and have it in your hands the same day.

We are well respected at our local computer shows and have over 3000 satisfied customers who return to us all the time.  Our goal is to have every customer feel as if they are part of our family.

We have many national and local computer repair and service companies, who use our services and our parts to handle all of their tough jobs.

We are a local company made up of all technicians who are all well trained in their fields, and have at least 5 years experience. Feel free to contact us with any issues you have and we will be more then happy spending a few minuets on the phone helping you.
