About Us



We don't just sell computers; we create solutions.
Sounds simple enough, but it's what sets us apart from others.
By buying, trading and selling refurbished and new computers,
we make sensible, powerful solutions that meet the majority
of computing needs.


If you need the biggest and fastest, we have new systems.
If you know exactly what you want, you might build your own
system from new, brand name, in-store components.
And if you need a sensible system at a great price, we have all
kinds of factory refurbished packages at great savings.


If you are a small business, call us for our unique solutions
to your unique problems. We will perform a full Information
Technology Analysis and recommend the right solutions.


Another unique aspect of OBriens Computer Service is
our experienced staff. Our sales technicians help you make your
buying decisions by determining what you need and suggesting
sensible solutions. Our service technicians are CompTIA A+ certified;
they really know computers and will gladly answer your questions.


We know... actually getting the right answer to a technical
question at a computer store seems alarming at first. But you'll
get used to it. Our expert sales technicians is a plus for everyone,
and the buy/sell concept is perfect for families, singles,
seniors and students, but it's the business client that first
attracted OBriens Computer Service.


For answers to concerns about buying refurbished or used computers, contact us.
