The Thermaltake Ceres 300 TG ARGB Mid Tower Chassis has caught my attention as a solid option for my next PC build. Here’s a quick rundown of what stood out to me:

  • Perforation: The case maximizes airflow with a whopping 55% of its panels perforated, promising to keep components cool.

  • Fan Configuration: Comes pre-installed with two front CT140 ARGB Sync Fans and one rear CT140 Fan, offering both aesthetics and functionality.

  • RGB Lighting: The RGB sync with major motherboard brands like ASUS and MSI adds a touch of customization.

  • Build Material: A combination of a 4mm thick tempered glass side panel and SPCC (Steel, Plastic, Copper, and Chrome) build gives it durability without compromising on looks.

  • Design Elements: The seven rotatable PCIe slots add a degree of flexibility that is not often seen.

From the get-go, I appreciated the sleek design. The black color is discreet enough for a professional setup but also perfect for a home gaming rig if that’s your thing. Materials are top-notch, and that thick tempered glass side panel feels sturdy and adds a premium touch. I’m big on keeping my rig cool, and I’m impressed with the abundant airflow courtesy of the perforated panel design.

However, despite the positives, every rose has its thorns. I noticed the absence of USB-C on the case I/O, which in this day and age feels like a miss. Also, while cable management is essential, the pass-through holes appeared somewhat small, and the lack of grommets didn’t go unnoticed.

For those who have beefy graphics cards, take note: the power splitter on some larger 40-series GPUs can get a bit cozy with the side glass. It’s manageable, but worth mentioning.

I appreciate the rotational PCIe Slots; they offer versatility to display your GPU the way you prefer. While optional items like the LCD display can rack up the bill, the customization options they provide do add value in my book.

Now, for as much as I admire the black tempered glass, smudges do show up easily, so keep that microfiber cloth handy.

On balance, the Thermaltake Ceres 300 strikes me as a well-thought-out case. It presents a blend of style, functionality, and potential for personalization that makes it stand out in a crowded market of mid-tower cases. Sure, it’s not perfect—no case is—but it certainly hits the mark on many levels for both amateur builders and experienced enthusiasts alike. For those looking to showcase their build and keep their system adequately ventilated, this could be a winner.

Cooling Efficiency and Fan Configuration

When assessing the Thermaltake Ceres 300, one of my key considerations is how effective its cooling capacity would be, especially under the duress of heavy gaming or intensive computing tasks. The case is fitted with two CT140 ARGB Sync fans upfront and one CT140 at the rear, creating a setup primed for excellent airflow. The fan configuration is significant for maintaining optimal hardware performance, and here’s what I’ve found:

  • The prevalent perforated panel design augments airflow significantly.
  • Fans can be easily synced with my motherboard software, helping to maintain a cohesive look.
  • Pre-installed fans mean one less thing to worry about during the initial build.

Early into the build, the airflow really stood out as a strong feature. With up to 55% of the panels perforated, there’s a substantial increase in air intake and exhaust potential, helping to keep the temperature down. The upfront effort to maximize cooling is clear, and with space for additional fans or even a larger radiator setup, the Ceres 300 feels like a breath of fresh air - literally!

The flexibility in cooling options is quite the boon: you can either max out the fan capacity or opt for a more extensive radiator-based cooling system. Having the ability to fit up to a 360mm radiator at the front and 280mm at the top provides a versatile foundation for however you want to manage your thermals.

Despite these positives, there are a few considerations to take into account. For instance, the lack of USB-C on the case I/O is a tad disappointing given its ubiquitous nature in current tech gadgets. Furthermore, the absence of cable grommets and the smaller pass-through holes could present a slight challenge during cable management, potentially detracting from the overall neatness of the build.

The pre-installed fans, although a great feature, do make me contemplate their longevity and the implications should they require replacement sooner rather than later. But the fact that these fans are ARGB and their lighting can be controlled via common motherboard software is a significant plus, offering both cooling and customization without additional expenses.

Overall, the Ceres 300 strikes a fine balance between its pro-airflow design and the flexibility for customization. It adeptly addresses the core needs for high-performance cooling while offering a personal touch through ARGB control. It’s not without its minor lapses, but these don’t significantly detract from the otherwise capable and dynamic cooling solutions the case offers.

When it comes to building or upgrading a PC, the case you choose is a cornerstone that supports everything else. I’ve often found that a case can either simplify the process or make it a headache, depending on its design. With the Thermaltake Ceres 300 TG ARGB, there’s a lot to appreciate in terms of expansion capabilities and ease of build. Let’s break it down:

  • Flexibility with Motherboards: Fits Mini ITX up to E-ATX, which means it’s versatile whether you’re building a compact system or a powerhouse.

  • Ample Room for Cooling: Space for up to five 140mm fans or a 360mm radiator at the front and a 280mm at the top, making it a cool haven for overclockers like me.

  • Rotational PCIe Slots: These can be super useful for an aesthetically pleasing vertical GPU mount, although you need to grab an additional riser cable.

  • Ease of Access: The hinged side panel is a dream, making it easy to tinker with the internals without the hassle of removing screws every time.

But every rose has its thorns, and even the Ceres 300 isn’t perfect. The lack of USB-C on the front IO is a miss, especially given how common the port has become. Also, the cable passthroughs are a bit small for my liking, and I do wish they came with grommets for a cleaner look.

Expansion-wise, this case supports my future ambitions for the build. The seven expansion slots mean I have plenty of room for additional PCIe cards. More importantly, they have a patented rotatable design, which offers an interesting option for configuring multi-GPU setups or other expansion cards in a more customized orientation.

Something else I appreciate is the storage options. While the market is clearly moving towards SSDs, it’s nice to have the option to install a 3.5” drive without sacrificing too much space. And speaking of space, while the case feels compact, the interior is surprisingly spacious—there’s room to maneuver without feeling cramped, which is a big plus when you’re connecting cables or installing large components.

The build quality is also reassuring. While the case might have some flex here and there, it doesn’t feel flimsy. It strikes a good balance between being lightweight and sturdy.

In terms of drawbacks, I’m a little concerned about the sharp metal edges internally—nothing a little caution can’t fix, but worth mentioning. And, while I love the RGB lighting, it’s a bummer that one of the pre-installed fans at the back isn’t ARGB. It doesn’t break the build, but consistency is key for visuals.

For those looking to add a personal touch, the optional LCD display is a nice touch, though its price may be a point of contention.

Wrapping up, the Ceres 300 gives me the flexibility I need with a straightforward building experience. It’s not without its minor issues, but overall, it’s a strong candidate for those prioritizing expansion and ease of build in a mid-tower case.

Value for Money and Overall Impressions

In terms of value for money, the Thermaltake Ceres 300 TG ARGB Mid Tower Chassis ticks most of the boxes you’d expect from a case at an affordable price point. This isn’t just a budget buy; the features offered here suggest careful consideration for gamers and builders who want flexibility without breaking the bank. Here’s a quick rundown of my key takeaways:


  • Excellent airflow, thanks to a high percentage of perforation and the option to install numerous fans or radiators.

  • Pre-installed ARGB fans provide both cooling and customizable aesthetic appeal.

  • Flexible motherboard compatibility, welcoming everything from mini ITX to E-ATX.

  • Tempered glass side panels add a premium look.


  • Lack of USB-C on the front I/O panel might be a miss for some who need this more modern connectivity.

  • Cable management could be better, as the passthrough holes are small and without covers, which could make certain setups look untidy.

  • Some minor build quality issues, such as the gaps between the side window and front panel, may bother perfectionists.

From a personal standpoint, I appreciate how the Ceres 300 balances enthusiast-level features with ease of use. The rotational PCIe slots and the potential inclusion of a 3.9-inch LCD (though costly) showcase its leaning towards modern, custom builds. The case feels solid, and the ease of removing panels and installing components is commendable. However, I was a bit disappointed by the absence of USB-C on the case I/O and the lack of grommets for cable management.

Moreover, while the fans are both quiet and efficient, the installation of a larger GPU could lead to some issues with the side glass panel; a right-angled adapter could be necessary for some builds. I also find the vertical GPU mount limitation a slight downside, as it requires the official Thermaltake riser cable for proper alignment.

The mesh front and magnetic top filter ensure dust doesn’t become a significant issue, maintaining those fantastic temps contributed by the fans. On the other hand, the possible misalignment with some larger GPUs in the back could cause a bit of frustration during the assembly process. Also, not having USB-C ready out of the box feels like a missed opportunity to future-proof this otherwise flexible case.

In summation, the Ceres 300 offers a spacious interior, a sleek design, and versatile fan/radiator support at a price that’s hard to argue with. Yes, there are some minor drawbacks, but nothing that can’t be fixed with a bit of ingenuity or compromises that not everyone will mind making. In my view, the advantages far outweigh the inconveniences, placing the Thermaltake Ceres 300 squarely in the “great value for money” category.
