The owner and staff of Extreme Systems are great, enthusiastic folks that went way way beyond anything I am accustomed to when it comes to "customer service." The Owner took a look and helped me set up the BIOS for a computer I built even though I probably only bought 25% of the components at his store, however prior to those purchases he already volunteered to help me out.
Our service agreements are designed to "proactively" maintain and update your network and computer systems. Preventing a crisis before it happens can be far less costly than trying to put it all back together again after the fact. A technician will come to your location on a monthly basis and perform a system analysis of all computers included in the agreement.
Keep the electronics & computers out of our landfills. That is the goal of the electronics recycling program launched by Extreme Systems that allows customers to recycle electronics free of charge. Having worked the last 25 years in the computer industry Greg Moore, the owner of Extreme Systems, knows the toll that throwing away "useless" electronics is having on our environment.
There are several actions you should take: 1. Purchase up-to-date Antivirus Software. My current favorite is Norton Antivirus. New Antivirus programs have better technology for scanning email as it comes in, updating themselves easily, and finding virus like activity, even if the virus has not yet been recorded.

Extreme System and their personnel are OUTSTANDING! I brought an IMac thinking that is way too old (2011) and nonetheless they hook me up with SSD and ram on the spot (no need to order parts). The system was too slow to at the minimum change the language from spanish to english and in less than 48 hours the computer was completed even with the latest updated. Im proud that I choose them and is the first of many. Im very impartial and they surprised me with an excellent customer service and technical expertise.

I had a wonderful experience in the store. The owner helped me out alot and was very understanding. I bought a new laptop and had it upgraded right in front of me. He was also able to trade in my old one and gave me a fair deal on it. I highly recommend anyone to come and see this store and if you need any upgrades or fixes come see them. It's a family operated business and very friendly. I normally never leave reviews however this place made me want to leave one

Brought in my custom built PC. Had a lot of expensive components but they didn't work together well and weren't performing how they should. Greg sat down with me, went over what I wanted from my PC, expectations, price, and style, and rebuilt my computer into the ultimate gaming machine. Fully liquid cooled and insanely fast. Couldn't recommend their services enough

This is the best place you can go to for any builds. They will build you anything that you bring in no matter how difficult it can be. They are professionals and know what they’re doing. They can get your computer up and running in a very quick time. Everybody is trustworthy and nice. I would come back again.

Extreme Systems is not simply a computer store located in Killeen, Texas and near Fort Hood--IT IS THE COMPUTER STORE!!!! I am not someone who usually writes reviews for local merchants, but in this case I had too.
You see, Greg the owner and Mike, his partner, are not simply two guys who decided to open a computer store--these are two gents really love to build desktop computers and laptops to your personal specifications (computers gamers--hint, hint!!!) and will do some at a reasonable price.
There is no glitch they cannot diagnose and fix. There is no computer resurrections they cannot

I was on a prebuilt since 2018 and I went here with my friends because they bought a few parts from the store before. I didn’t know much about building PCs except watching YouTube videos and they were really helpful with everything. I tried building my pc with my friends and the motherboard and cpu ended up being faulty. I took it back to them and they troubleshot the problems and I got the system back in a day. They replaced the parts for me and sent the faulty parts back even though they didn’t have to and built the system, because I didn’t want another issue to pop up, and it came out

Greg and his crew have always been there for our computer issues. They do FREE diagnostics if you bring in your computer. This lets you know if it's a comp or network issue. If they can't help, you don't pay anything but they'll try to help any way they can. They built a custom computer for us with high end graphic card, I bought a new laptop, and we've purchased other products. They sell (new and refurbished) computers of all kinds, install, service, even have an awesome virus protection and maintenance package. Their website has current comp threat info to stay up on

I brought my computer in to be serviced because it ran slow, the tech took about 5 minutes to check and diagnose the problem. I left my lap top there early in the afternoon and they were finished repairing before they closed (SAME DAY)! I found them to be professional and my laptop is running much quicker, they even cleaned the keypad of the food and dust (I didn't ask them to but I'm glad they did). I also want to note they offered a two year warranty on their repair, I would recommend them to anyone!
