    • Obviously built to be a long-term investment.
Size: 3700X | 3070
I ended up with the Ryzen 3700/RTX 3070 build at a seriously amazing price right before the shortages quintupled the price of an RTX 3070. PRO: - This system is a QA beast. So, let me attest that Thermaltake's build quality on my system is the best I've seen of any prebuilt desktop in my 30 years of owning PCs. None of the components were loose or janky, and I was able to pull the packing materials away from the system with no debris on the system. - Out of the box, this system uses nowhere near the 650W the PSU is capable of pulling. That plus the PSU's gold rating has protected everything during two outages thus far. I still intend to buy a UPS, but knowing Thermaltake went above and beyond for the PSU says Thermaltake intends these machines to be long-term investments for every customer. - The GIGABYTE RTX 3070 OC 8G is one of the most reliable and finely tuned 30-series cards on the market. It's factory OC'd to 1815Mhz and can easily be OC/UV to that performance at .875v. Afterburner has full support for unlocking, custom fan curves, limits, and more. CON: - The open case has advantages and disadvantages. If you live in a clean house, the open design is perfect. If you live in a house where people think "dust on the table" is a remix of the song "Dust in the Wind," you'll need to use an air blower every month or so. That said, I have had NO issues with performance or static electricity risking components. Thermaltake did an insanely good job making sure this build doesn't have shortage risks from a little dust buildup. - The lack of accessories for this case is frustrating. It's a modular case, but I'd have to buy a whole separate tower to get things like the extra glass panels to fit to the sides. This is leading me to want to replace the case altogether for something more traditional. Lastly, THINGS I WISH WERE INCLUDED: - Information on installing full liquid cooling. I would love for a Thermaltake-approved guide on what to buy from them to replace the RTX fans and the CPU liquid cooling with a full liquid cooling setup. - Recommended accessories. I'd like a list of suggested self-upgrades for my system. If I want to add a second NVMe, what would Thermaltake recommend? Would Thermaltake recommend additional RAM? What are some recommendations I can have that give me something fun to look forward to with this system? This is an investment, right? How can Thermaltake help me evolve this system over time using new components or other products in the Thermaltake shop? - I would pay big big bucks for Thermaltake to give me a detailed video walking through the AORUS B550 BIOS settings, how to update the RTX 3070 BIOS, any nifty features or advanced tips. Stuff that's just between Thermaltake and its customers. Everyone who buys Razer gets this "club" treatment, and I want to be in the Thermaltake Club. ... show more

    • Faulty psu and terrible customer support
Size: 14700KF | 4070Ti S | 32G D5
When I bought the Thermaltake LCGS Reactor i7TS, I expected a reliable prebuilt system from a reputable brand. What I got instead was a fire hazard of a power supply and one of the worst customer service experiences I’ve ever had. Within just a few months of light use, the PC began tripping my circuit breaker—every single time I plugged it in. After extensive troubleshooting, testing outlets, breakers, and even removing the PSU entirely from the case, it was clear: the PSU itself was the issue. On closer inspection, I found what looked like burnt or melted components inside. Naturally, I contacted Thermaltake support expecting a straightforward PSU replacement under warranty. Instead, I was told I had to send the entire PC back—including drives with personal data—just to replace a single, clearly faulty part. Despite me doing all the legwork to isolate the issue, they refused to accept that only the PSU needed to be replaced. Their support emails didn’t inspire confidence either—full of spelling errors, poorly written, and lacking any professional tone. If they can’t be bothered to proofread an email, it makes you wonder how careful they are with actual hardware and RMAs. Update (Over a Month Later): After nearly two months of back-and-forth emails, they finally sent me a replacement PSU. I had to argue with them to avoid shipping the entire system back, and even then, the process was a mess. They told me the part would arrive on a Monday, didn’t ship it until that Monday, and it didn’t arrive until Friday. So I was without a usable PC for multiple months—just because they refused to send out a single component when I first reported the issue. To make matters worse, they got my shipping address wrong multiple times. I had to send them the same correct address repeatedly. At one point, they sent me an email asking “Is this okay?”—with my own name listed as the city, the wrong state, and the correct zip code. How does that even happen? Yes, I finally got the replacement PSU. Yes, once I installed it, the PC worked fine. But for a high-priced prebuilt from a known brand, this should never have happened. A power supply failing in just a few months is unacceptable, and the RMA process was an absolute nightmare. If you're thinking, “Hey, it’s a prebuilt—it’ll save me time and hassle,” think again. I ended up doing more work troubleshooting and arguing with support than if I had just built it myself. Bottom line: Avoid. Not worth the risk or the customer service headache. ... show more
