I am writing this a few days after receiving my new CyberPower PC. It looks great and it plays great. So I am filled with the initial euphoria that often accompanies seemingly good products. Maybe after a few months, or after a couple of years, I will feel differently.  
 
I bought the Gamer Infinity 8800ProSE, but don't focus on the name. The unit is customizable. I had CyberPower replace a large 7200RPM hard drive with a smaller but faster WD VelociRaptor turning at 10,000RPM. And they replaced the default ATI video card with an NVidia GTX 295, more expensive, but faster. Other impressive components include an Intel i975 Extreme Edition CPU with liquid cooling, 6GB of DDR3 memory, and a Lite-On Blu-Ray DVD player.  
 
I did not put the high-def sound to test. After uninstalling the RealTek drivers and disabling the onboard sound, I transferred a Soundblaster X-Fi Extreme Gamer that I had been using with my old PC. I doubt that ANY onboard sound can equal its quality. But keep in mind that this is not a complaint. I have RealTek on a laptop, and it IS good sound. CyberPower keeps its retail price down by excluding a soundcard from its default configuration. That's a good thing.  
 
The network adapter works quite well and is speedy with the Siemens SpeedStream 4100 DSL modem that I use with AT&T Yahoo! Though I have no use for it, a PCI wireless card and an attachable antenna are also included.  
 
Refreshingly new for me, and perhaps most impressive of all the components, are the case and the fans. A huge fan on the side, a huge fan on the top, which is ventilated (something I have never seen before), and two big fans on the front, make the interior of my new PC seem like the windy city of Chicago. And all the fans have electric-blue lighting that goes well with the case's black color.  
 
I had reservations about only one thing: the power supply unit. I live in downtown Los Angeles in a room without air conditioning. Over the last few years I have had two power-supply units fail because, I believe, of overheating. I replaced them both with dependable PSUs made by PC Power & Cooling. (Their fans turn at an exceptionally high speed, which keeps their PSUs from overheating and which gives them a long lifespan in hot temperatures.) CyberPower did not give me the option of replacing their 800-watt PSU with one from PC Power & Cooling. But to be fair, only time will tell whether or not CyberPower's PSU can endure.  

I got exactly what I asked for and it was here exremely fast. I have always purchased pre-built computers. There has always been something about them that I would have changed if I had had it built myself. Configuring my own computer was a wonderful experience. CyberpowerPC made it easy and I loved the amount of options made available to me. I could go as cheap or expensive as I wanted with no sales people telling me I need this or don't need that. I could pick and choose at my own rate and go back and change whatever I wanted because I can save my configuration. So far this system is everything I asked for. No problems whatsoever. My daughter has worked for a major electronics chain for many years. She said that this is much more of a system for the price than anything they had. She says there is no way they could compete even with her employee discount.  

This is my first time ever to leave a negative feedback. I ordered a custom PC from CyberPower. It arrived defective (never worked). I followed phone support and disconnect-reconnect memory, video card, etc. It still gave no response. No video coming out, no hard drive response, and the disc drive no response either. Cyberpower claims they burn-in every PC, but my PC only finished assembly, QC and shipping in one day (I check order status frequently). I seriously doubt every PC was checked. Then I found the fine line CyberPower uses "new or equivalent to new part". If you do not mind using half-new product, cyberpower is fine. I do mind, so I decided to return the PC. The worst part is that CyberPower refused to reimburse the shipping charge. Come on, I returned not because I changed my mind. I paid $734.35 for a new functioning PC, not a defective product that requires warranty right away. Basiclly, I had to pay $50 to return the defective new product. I am electronic fan and do a lot of online shopping, CyberPower is the worst online store I had experience with.  
Now I understand why there are so many polarized ratings about about CyberPower. If some are lucky and did not encounter the problem, the price is very good.

Ordered two computers from cyberpowerpc. Extremely happy with customer service and product! Definately recommend to others.

CyberPower PC provides convenient purchases as well as use of their website. They stand behind their products and provide efficacy. I would definitely recommend for future computer purchases.

Very pleased with my purchase, however I made my purchase at the start of the school year and Cyberpower was a little late on the build and shipping and there were some parts unavilable which slowed my order.

Really a great place to buy a computer and fun tool. You pick all the parts...case, MB, Memory, Video Card Etc and then Cyberpower builds it. They did an excellent job on my computer. It was everything I picked and worked great out of the box. They even let me change some things over the phone with their great customer service. The shipping was fast and on time. I will for now on use Cyberpower PC to build all my future computers. Thanks for a great experience Cyberpower!

Fantastic machine. Came extremely well packaged, everything was in nicely put in places inside of the computer, and above all, everything worked. I have used my new computer on a daily basis since it arrived, and there have been absolutely no problems with it. It arrived on time and looked like it had been treated with absolute care. I will definitely be doing any future business with CyberPower.

Great company this is my 3rd computer I bought from CP and will not be my last ...astrid was a great customer rep and she helped me upgrade my card from a 285GTX to a 5870 which just came out she gets a 10+ from me !!! just kind of bummed becuse I havent heard anything about my rebate for get the windows upgrade yet :( ....guess i will just need to call to check into it.

This is the 3rd system I've purchased from CyberPower... I've always had good, prompt service both technical and customer. I've recommended CyberPower to friends and bought a system from them for my sons. No complaints, no problems getting help when problems arise. Good job overall.

I ordered my computer on 10/27/2009 and received it on 11/02/2009. The computer came to me via UPS in a well packed box. I opened up the computer and inspected all componets and found everything that I ordered. I paid for the custom wiring and they did an outstanding job. The only thing is they tied some of the wiring to the removable HD rack.. I would have to cut the ties to get the rack out. NO Biggy! Still an outstanding job on the wiring.  
 
When I removed the case from the box I heard a ratteling sound coming from the top of the case. I had to take apart the case top and what I found was a screw!! Quality control or the packing department should have noticed the rattle!!  
 
I have been running the computer 24/7 since 11/2/2009. It is very quite and have had no problems with any of the componets. So far all my applciations are runnig at top speed.  
 
I have had no communcitions with Cyberpower other than placing the order online. Received an email that they recieved the order. Went online and followed the progress. I found their pricing to be very competitive and their componet selection was great.  

One great machine. Runs programs smooth and fast. Runs the game programs with no problems at all. Plus with the purchase, they gave me a coupon for windows 7 at no cost to me. I went online and was able to put it though with no problems. The tower and monitor looks great and when the tower is turned on you can see the inside of the computer light up, looks awesome, like it is alive. I would highly recommend them if you are looking for a computer, it is easy to build it the way that you want and is tested and delivered fast.

This was one of the first Windows 7 builds, so perfection was not expected. However, the only issue was a sound driver, which was fixed by an automated update download, and the system worked flawlessly.  
 
Cyberpower has a site that allows you to customize various builds until you find the optimal configuration for you and your budget.  
 
This is our family's second purchase from them, and although this is a very early report on the second unit, they appear to be the 2 best computers we have ever owned.  
 
Cyberpower really delivers on value.

Excellent service and great product, this computer is so fast I can't believe it. Everything was put together as asked and it was sent faster then the estimated ship date.  
 
Thanks!
