  • A Gaming and Design Beast
Size: 32GB | 512GB NVMe + 2TB | RTX 3060
I use my system primarily for Graphic Design and Gaming. After 6 years I figured it was time to upgrade since I was starting to play games that I had to drop down to "High" or "Medium" graphics quality. I was honestly surprised at what a big difference the Mantis made in not only games but video editing and graphic design programs in general. The 32GB of ram, SSD and 2080 combine to make a flawless experience so far. I am currently playing Red Dead Redemption 2 and there is a stark difference in both quality and FPS compared to my older system (I7, 16gb ram, 4GB Geforce). I did a fair amount to research and ended up comparing the custom home build versus this Mantis. I came up with the Mantis costing $150 more. My time and aggravation is worth more than $150 so I pulled the trigger. I am glad I did. The components are top notch, the power supply is overkill and the thing looks cool as hell. There are other choices out there and some by the same company but nothing that I could find was the perfect storm of power + price that this system embodies. ... show more

  • Best computer I ever bought!!
Size: 32GB | 512GB NVMe + 2TB | RTX 3060
Actually, this is the FIRST desktop computer I have ever purchased. I have always built my own systems, but now at 81 years old, decided to just find something that will last into the future. Boy am I impressed with this!! I can't seem to find anything bad to say about it. It is fast, quiet, good-looking (just like my ex-wife) and I am so looking forward to the new Microsoft Flight Simulator coming later this year to see how well it performs. I only have good things to say about this computer and CUK!!! ... show more

  • With the price of graphics cards right now this is a great value for what you get
Size: 32GB | 512GB NVMe + 2TB | RTX 3060
I am extremely happy with this purchase. The computer runs like a beast. Even with a 3070 graphics card the temp stays cool. It didnt come with a bunch a bloatware on it. I had a small issue where the HDD wasnt showing up (it came unplugged during shipping) and the company responded to me the same day and helped troubleshoot the issue. It runs some of heavier games right now like cyberpunk 2077 no problem. The only thing that needed an update was the graphics card driver. It came with all the hardware named in the specs. With the price of graphics cards right now this is a great value for the money. ... show more

  • Handles VR smoothly.
Size: 64GB | 1TB NVMe + 2TB | RTX 3090
I didn't have time to build a machine for an update of my VR system and decided to by a pre-built and designed system. Figuring out all the interdependencies and compatibility of different vendors parts can take some time, which I didn't have. This machine provided a one stop solution with the latest graphics power and concise build that I needed. I added a couple of USB3 cards to the system in order to handle the extra power and port count that VR systems sometimes require and are not available on any motherboard, but that is common to all systems I have seen. The good new is that the slots are there for upgrades. My machine was built with the Zotac version of the GFX card and the MSI MB with a 850W Toughpower PS, enough for the USB power demands. It came with the extra PS cables that weren't needed for the initial build so I didn't have to chase any down for the USB3 board additions. The extra memory and storage sizes are a plus as well. The only drawback is that the 120mm case fans are a little weak, but can easily be changed out for different fans if needed. the power line touting is easy to get to for fan replacement. the machine is a little pricy, but 3090 GFX cards are scarce right now and are also pricy. ... show more

  • This is an amazing computer
Size: 32GB | 512GB NVMe + 2TB | RTX 3060
Showed up a day earlier than expected and was packed very well. No fear of damages at all. The only problem found was the hard drive was not plugged in. It didn't appear to have been shaken out because if it had been properly plugged in, it would have (or should have) been tight enough to stay fixed. Regardless, it is something that should be inspected when purchasing such items after a trip across several states. The carriage for the drive was also a little detached but very small incidental issues. Overall...this computer is a rocket and has been performing exceptionally well and will gladly tell others to consider buying from CUK in the future. All considered I think the price could be a touch lower but happy regardless and would purchase from CUK again. I didn't rate tech support because we have not dealt with them yet but I can imagine they are as good as the product they produce. ... show more

  • Customer Service is Exceptional!
Size: 64GB | 1TB NVMe + 2TB | RTX 3090
I've had the unit for a couple of weeks now and as far as the performance and quality of assembly I am more than pleased. Its exactly what I hoped for. Taking into account the current going rate for the 3090 cards the price was very comparable to ordering all the parts and factoring in the time it would have taken me to put it all together. There was a problem. The item was damaged in shipping. Cosmetic damage only, it was very well packed and not the shippers fault at all. From the packaging it looks like it took one solid drop on a corner that jarred it just enough to snap some of the mounting brackets on a exterior panel. When I reached out to CUK they were prompt with a response and updates as to the status of our resolution. We came to a solution that I am very happy with. ... show more
