We've been using these guys for years. They are the ultimate professionals. They understand you need your machine back pronto. Unlike so many "nerd shops'" COI understands your needs-- and unlike others, they understand the importance of communicating status back to the client. This a a boutique operation run by skilled technical and business professionals. It's kinda like the Tiffany's of hard-drives. Highly recommended!

Joe and Jim are fantastic. They helped me upgrade my PC from a FX 6300, GTX 950, and a old motherboard to a Ryzen 1600, ASRock motherboard, GTX 1060. The process took a full day and I was able to pick it up the next morning. It's nice to have them so close to my house and they were on the phone with me for problem solving (which was my doing). Joe is vary knowledgeable and gave me the run-around of everything.

They both helped build my tower and Jim even had no problem carrying my PC case in and out of the shop (which is lovely by the way). I'm extremely satisfied with the build and will definitely be coming back for upgrading again. Do not hesitate to ask what you might think as a "dumb question" - there isn't any! Thanks guys! UPDATE* - 7-27-21 Joe is mad scientist!

I come in about every 6 months for upgrades. Remember that word, UPGRADES not fixes he's always working on things and gets the job right. He, like myself wants your machine not only to perform right, but look great at the same time. Here's some of the stuff he's done recently. I moved recently and I drive my PC about 40 mins to get here. It's worth every mile. You the man Joe!

My hard drive took a dump on me, and I don't have time to to fix it myself. Coi computers fixed it with no problems, and provided excellent customer service. I also, paid less then I had expected. If you need computer work done you don't need to look any further!

I'd like to highly recommend Joe at COI Computers in Glendale for your computer issues. Just used him twice in the last month - first to replace the hard drive on my laptop - and then to recover hundreds of photos I thought I'd lost forever from an SD card I accidentally reformatted. Pics were from a road trip I just did with my son whom I helped move to Denver, and more from the subsequent road trip I took through WY, UT, NV & CA. Joe is very knowledgeable, friendly and was a pleasure to get to know. Thanks again, Joe!

Joe and his team at COI are your go to company for all your technology needs. I have used COI 20 + years for commercial and personal services. They can assist you on hardware, software, networking and security. Personal, professional, proficient @ competitive pricing for the value.

Joe did fantastic with helping build my tower. He was very knowledgeable and explained things well for someone like me who isn't very tech savvy. Their work is amazing quality that is hard to find. If you need something built or have questions this is the place I'd recommend to novices and pros alike!

I just want to say that this is the first time in many years that my computer actually has ran flawlessly for over four or five months without having someone else work on it. Before going to COI computers I thought that I would have to spend another $1500-$2000 for a new computer. However this was not the case with COI. The staff is very friendly and they take the Time to evaluate your computer without spending a lot of money.

I highly recommend repairs and/or purchasing computer technologies from COI computers. Their service department was super fast and my computer was returned within a few hours and working amazing. All the best, Mike

Called the shop to do some basic troubleshooting on my gaming PC and spoke with Joe. Joe is very knowledgeable on everything I asked him about. Just from talking to Joe over the phone, I would rather go to COI Computers for anything PC/troubleshooting related, instead of Fry's Electronics. Joe was very personable and gave me confidence in what went wrong in my PC. Very glad I spoke with Joe today! Gave me peace of mind on my hardware

What a great experience. The two gentlemen who helped me were VERY knowledgeable and explained to me every step of the way what they will be doing and why they are doing it. They fixed my pc overnight and at a very reasonable price. 3 other PC shops / techs couldn't figure it out but they solved it instantly. 5/5 every day of the week for COI Computers. If you have a custom pc that needs repair or want one built you wont go wrong here.

Joe added a new hard drive and RAM capabilities to my MacBook Pro for under $500, thus saving me from purchasing a new MacBook immediately. My laptop runs like a new one, and allows me time to purchase a new one. Exceptional service and possibly one of the finest individuals you will meet. Well done, Joe! Thank you very much!

Moved here from out of state and had computer equipment damaged in the move. COI was fantastic to work with when I needed repairs fast and didn't know anyone in town. The rates are inexpensive and they have a professional and informative way of providing customer service. I will continue to use them for my computer repair and will recommend them.

I fought with online help for a couple hours. Fed up, I put the Computer on the front floor of the pick up and drove the few miles to the office of COI Computers. Joe DeMichael repaired the problem quicker than it took to pay him! Awesome. I am back to work in the time to drive back home. Got an IT problem, call him.

I have been doing business with Joe from COI computers for over 8 years. My family has been coming here for even longer than that, and we have always received 5 star service. Joe is always honest with his business and is truely there for you and your needs. Anything from building a computer to repairing them, he is the master. I travel from the opposite side of the valley just to come here. The work is always done quickly and with more than fair pricing. Thank you Joe!

As a non-tech person, I have fully trusted in Joe and COI Computers for years. They ALWAYS understand my computer needs even before I do. And, I've witnessed over the years how they treat their clients first hand, going above and beyond. Injust can not imagine working or trusting anyone else with my computer needs. Thanks Joe for taking good care of everything. I truly appreciate it. A real professional!

Purchase my new desk top from them. Will never go anywhere else. No pressure. They build what you need, no extras unless you want them. A bit pricer than other retail but well worth it.
