The sharp, geometric design of the Reactor 7897XS stands out on any desk, and it’s obvious the build is all about airflow and cooling. After some long gaming sessions, temps stayed steady, and the desktop chewed through modern titles without stutter or slowdown.
- AMD Ryzen 7 7800X3D CPU, B650 Chipset Motherboard, 32GB DDR5 5600MT/s RGB Memory, 2TB NVMe M.2, WiFi
- AMD Radeon RX 9070 XT, Display Port/HDMI
- Enjoy Panoramic Views with 3mm TG Front panels and Excellent Airflow with Perforated Side Panels
The RGB lighting pops just enough for some flair, and the case does a surprisingly good job of keeping things quiet, even when the action ramps up. It’s hefty and definitely not compact, so you’ll want a proper gaming space for it. Setup’s painless, and all the main ports are right where you’d hope.
Overview: Thermaltake LCGS Reactor 7897XS Gaming Desktop
Out of the box, the Reactor 7897XS grabs attention with its octagonal chassis and see-through front. Not just for show—this shape helps with airflow, so it doesn’t get too toasty when you’re gaming for hours.
Multitasking and gaming both run without a hitch, thanks to the beefy AMD processor and graphics card. Fast DDR5 memory and a roomy NVMe drive keep everything snappy—games load in a blink. On the flip side, it’s big and heavy, so if you’re tight on space or picky about desk aesthetics, maybe give it a second thought.
Pros:
- Strong graphics and processing
- Fast storage and memory
- Good cooling
Cons:
- Odd shape can be awkward
- Heavier and larger than a lot of desktops
Cutting-Edge AMD Ryzen 7 7800X3D Processor
At the core, the Ryzen 7 7800X3D feels genuinely fast in both gaming and multitasking. Even when things get hectic, the CPU keeps its cool—no stutters, no lag.
It pairs nicely with DDR5 memory, making switching between tasks a breeze. You might pick up on some fan noise when it’s really working, though—that’s just the trade-off with this kind of power.
Notable points:
- Quick game launches, smooth task switching.
- Stays speedy, but fans get noticeable under load.
So, the 7800X3D is a powerhouse, but if you’re super sensitive to noise, you’ll want to keep that in mind.
Advanced Radeon RX 9070 XT Graphics
The RX 9070 XT handles demanding games at high resolutions with ease—frame rates stay high, and visuals are crisp. Stutter is basically a non-issue, so gameplay feels reliably smooth.
That said, the GPU’s fans can get loud when you’re really pushing it, and it does throw off some heat. Ray tracing works, but honestly, it’s not always quite as slick as some high-end competitors at ultra settings. Still, for most games, the RX 9070 XT gets the job done and then some.
High-Speed DDR5 RGB Memory and Storage
Fast memory is always a plus, and the DDR5 RGB kit here means quick launches and a bit of extra glow inside the case. Even with a bunch of apps open, the system doesn’t get bogged down.
A 2TB NVMe SSD is plenty for most, with fast SSD bootup making startup and loading almost instant. Only catch? There’s just one drive bay inside, so if you’re a storage hoarder, you’ll need to think about external options.
Pros:
- Fast DDR5 with RGB
- Generous 2TB SSD
Cons:
- Only one internal drive bay—limits expansion
Innovative Octagonal Prism Case Design
Right away, the octagonal prism case is a conversation starter—definitely not your average rectangle. The glass front and sharp angles make it look modern, but not too over-the-top.
The design isn’t just for looks; airflow benefits from the well-placed vents. The wide base means it sits steady, but you’ll need more desk space than usual. If you’re working with a tiny setup, it could be a squeeze.
Pros:
- Eye-catching, minimalist vibe
- Better airflow from smart vent placement
Cons:
- Needs more desk space
- Shape isn’t for everyone
Superior Liquid Cooling System
Thermaltake’s liquid cooling is a highlight here. After several marathon gaming sessions, temps stayed in check, and fan noise was lower than most air-cooled rigs.
It keeps the Ryzen 7 7800X3D humming smoothly, even with heavy use. The only gripe? The tubing gets a bit cramped inside the case, so adding or swapping parts later could be a pain.
Pros:
- Stays cool under load
- Runs quietly most of the time
Cons:
- Tight interior makes upgrades tricky
Exceptional Connectivity Options
Plugging in accessories is easy—plenty of USB ports, including Type C and USB 3.0, and you don’t have to fumble around the back for everything. DisplayPort and HDMI are both there, so dual monitors are no problem.
Only minor letdown: not as many front-facing ports as some might like, especially if you’re a wired peripheral fiend. Built-in WiFi is handy, so you can skip the Ethernet cable if you want, though for hardcore gaming, wired is still king.
Pros and Cons
Pros
Performance is the first thing you’ll notice—Ryzen 7 and RX 9070 XT chew through games and multitasking with ease. No stutter, even with demanding titles or lots of apps open.
The 32GB DDR5 RGB memory is great for heavy-duty tasks, and load times are short. Liquid cooling keeps things from getting too loud or hot.
Build quality feels solid. Tempered glass gives it a nice finish, and airflow is clearly a priority. Setup’s simple, and front I/O (including USB-C) makes daily use less of a hassle.
Cons
It’s big and heavy—not exactly portable or ideal for a tiny desk. The RGB lighting is bold, too, which not everyone will love.
Fans can get a bit noisy under stress, and the tight interior makes upgrades less fun. The price tag is high, so it’s not for budget shoppers or those who don’t need all the bells and whistles. WiFi is decent, but if you’re chasing zero lag, wired is still better.
It’s a strong performer, but make sure you’re OK with the size, style, and cost before taking the plunge.
Customer Reviews
Most users seem happy with the Reactor 7897XS, especially when it comes to performance in gaming and multitasking. Build quality and speed get a lot of praise, and it stays pretty quiet under load.
There are a few complaints about the size—definitely not for cramped spaces—and some wish the RGB control software was more polished. Overall, if you’re after a fast, reliable desktop, feedback is mostly positive, with only minor gripes about setup and software.
Ideal Uses for Reactor 7897XS
This desktop is a great fit for gamers—it powers through demanding titles with high frame rates and quick load times, even with settings maxed out.
It’s also solid for creative work like 3D modeling or video editing, thanks to the quick processor and generous memory. The only catch is the bulky chassis; if you’re short on desk space, it might not be the best match. For basic office stuff or just browsing, it’s probably overkill.
If you want top-tier performance and don’t mind a big, flashy desktop, the Reactor 7897XS is worth a look.

How does the Thermaltake LCGS Reactor 7897XS perform in gaming benchmarks?
Thermaltake clearly had gaming in mind here. Frame rates are high at 1440p, and AAA games run without stutters or dips.
Cooling and hardware keep up with demanding titles, even at high settings. Lag is rare, and load times are short. Ray-traced games run well, though some CPU-heavy games might push temps a bit during marathon sessions.
What cooling system is used in the Thermaltake LCGS Reactor 7897XS, and how effective is it?
This system relies on a closed-loop liquid cooling setup with a 240mm radiator. In daily use and during gaming, temps stay reasonable, and the fans don’t really draw attention unless you’re listening for them.
If you push the system hard, there’s a faint hum from the radiator fans, but honestly, it’s not much to complain about. The airflow gets a boost from those perforated side panels and the roomy case, so heat doesn’t linger inside. For most people, overheating or throttling just isn’t something you’ll run into.
Can the Thermaltake LCGS Reactor 7897XS be easily upgraded?
There’s pretty solid upgrade potential here, mostly because of the case’s size and how things are arranged inside. If you’re the type who likes to tinker, removing a few screws gives you access to the guts—swapping RAM, adding storage, or even replacing the graphics card isn’t a major ordeal.
Still, it’s not all smooth sailing. The unusual shape and custom layout mean that installing really large GPUs or certain third-party parts could be a headache. And, be ready to wrestle a bit with cable management, especially near the power supply—there’s not a ton of room to spare.
How does the Thermaltake LCGS Reactor 7897XS compare to other pre-built PCs in its price range?
