    • Very nice gaming PC

This gaming PC is amazing in every way. The graphics card is top notch and works flawlessly with the motherboard, processor, and RAM. My use for this machine is multi faceted but mostly its use is for streaming and I have yet to push more than a 30% load at any given time running max graphics capabilities for streaming. The aesthetics are on another level with the RGB fan and RAM lighting, and the included program works great for dialing in exactly how you want your lights to display. (After updates it was necessary to re-install the ASROCK light program for proper functionality. Please ensure you're downloading the correct version of the utility if you run into this issue as well. The updated version works great.) The fans are not very noisy and the audible noise output is what I would consider a medium level hum for PC fans. This PC is sure to impress anyone who's into computers for virtually any use, and the price tag is low for how powerful and well functioning it is. For the reasons outlined in this review I give the Thermaltake LCGS Quartz i460 R4 Gaming Desktop my highest of recommendations! Purchase with confidence! ... show more

    • Honest opinion (may update)
Style: 14400F | 5060
Just got this PC a few days ago, so I will update this review if anything changes! But it was super easy to set up, and it came with really good packaging, the PC came in perfect condition. The computer has 3-4 fans inside and I have had zero issues with heating. It runs extremely well, I have had no lag what-so-ever. I have it set up connected through an Ethernet cable, but it can connect to the WiFi wirelessly as well. The build quality is amazing, love the LED lights— which you can change the color to! Downloaded my games very quickly with no problem! The sims 4, which used to take me forever to get downloaded, downloaded almost all the game packs and the main game within an hour and a half. For the first few hours of using the PC, it did have minor issues with using too much WIFI, but it fixed itself rather quickly (could have just been my provider). Overall, I have no complaints about this PC. I’m in love. ... show more

    • My GF loves it!
Style: 13400F | 4060
Bought this as a birthday present for my girlfriend and she loves it. She loves games like sims4 and her old pc couldn't handle all the cc and mods. She's loaded this new pc up with all the cc and mods she can find and it still runs flawlessly. Setup was quick. It runs real quiet and cool. Overall I would buy one for myself if I needed to. ... show more

I use this PC for everything. It runs all my steam games smoothly, including the big ones like rdr2. I can also have a dozen word documents open at once and this thing won't lag at all. I haven't found a limit for tabs open either. For awhile I had some coding classes and this had no problem running software like Arduino, etc. Its just all around very fast. I have a MacBook and this PC starts up and runs just as fast/smooth if not better. ... show more

    • Good value but inaccurate components.

I originally bought this because the brand itself had good reviews, it was very competitively priced and the component list came to about roughly the same price so it felt like a good value. Pros: good price, good cable management (minus one exception which I will elaborate on at the end), plug and play after initial updates, can run games such as Starfield on high settings no issues, runs quiet, fans run/stop when they are supposed to, plenty of usb/display ports and relatively easy to access if you want to install something like an SSD. Cons: The graphics card is not MSI such as the one in the picture, instead it’s a “Zotac Gaming” a brand that I’ve never heard of (which isn’t much of an issue since they are virtually the same on paper) There is one concern however, when I was mounting an SSD, I noticed one of the cables that plugged into the motherboard appears to be bending the outlet, it can be seen on the second and third picture. I am not sure if this is normal or what exactly that outlet powers, it appears it’s attached pretty well for now but it feels like the cable was pulled too tight when they were tucking away all the slack from the cables. Hopefully it’s nothing that comes loose in the future I will definitely reach out to the company to raise my concern. Overall I pretty satisfied with this prebuilt computer, I’ve been running WoW and starfield with no issues and I feel like I got a pretty good value in terms of price and aesthetics. ... show more

Looks good, price seemed right... but after I received it free from package damage... it would not boot pass the bios screen... called Thermaltake and they seemed helpful, guided me on a quick check of components. Nothing seemed to work. Called Amazon and spoke with a representative who told me that the item was not eligible for returns. I could either be refunded the money, or receive the almost 900 dollars credited to my account. I asked them to just refund, and I'll attempt to buy another from an in store company. 4 days later no refund... so I called again, this time to be told I'd have to return it... to receive a refund. I have already disposed of this item and it is no longer retrievable. So Thanks Amazon for telling me 2 different things and costing me almost 900 dollars. The PC was for my 14 yr old sons birthday. ... show more
