Overview

The Thermaltake S100 TG (model CA-1Q9-00S1WN-00) is a mini tower PC case that stands out with its tempered glass swing door on the left side. It supports Micro ATX and Mini-ITX motherboards, making it compact yet capable of housing a respectable gaming or productivity build. The all-black finish and clean lines give it a professional look that fits well on any desk. Inside, you can mount up to five 120mm fans and support 240mm radiators in both the front and top. The included rear 120mm fan ensures basic airflow out of the box. The swing door design provides easy access to the interior without removing the side panel entirely, which is especially handy for upgrades or maintenance. Positioned as an entry-level to mid-range case, the S100 TG offers excellent value for its price. It's a solid choice for first-time builders, compact gaming rigs, or space-conscious home servers.

Product Info

Released around 2020, the Thermaltake S100 TG is a budget-friendly mini tower case. It typically retails for around ¥4,650 JPY (approximately $35 USD), which is extremely competitive for a case with a tempered glass side panel and a swing door mechanism. The warranty is standard 2 years from Thermaltake. Market positioning: entry-level to mid-range. It's not a premium case, but it offers solid build quality, good airflow, and easy access. The steel frame with tempered glass is durable, and the interior is spacious enough for most mid-range components.

Best Use Cases

Compact Gaming Build Ideal for a Micro ATX motherboard paired with a mid-range GPU like the RTX 4060 or RX 7600. The case is small enough to fit on a desk, and the tempered glass showcases your components. The swing door makes swapping GPUs or adding RAM a breeze. → Not for: Enthusiasts wanting large GPUs (over 320mm) or 360mm radiators. You'll need a larger case. Home Office / Media PC With its small footprint, the S100 TG fits perfectly under a desk or in a media cabinet. It's quiet enough for daily tasks, and the clean design won't clash with your workspace. Pair with a low-power CPU and a fanless PSU for near-silent operation. → Not for: Users needing optical drives (no 5.25" bay). * Budget First Build At this price point, the S100 TG is an excellent starting point for beginners. The swing door simplifies motherboard installation, and the cable management cutouts make routing tidy. You can build a capable PC without spending too much on the case. → Not for: Those who prefer a larger, more spacious interior for easy cable hiding. The interior is compact, so careful planning is needed. ## Alternatives
Fractal Design Define Mini C A similar Micro ATX case with a focus on noise dampening. The Define Mini C has sound-dampening foam and a solid steel panel option, while the S100 TG offers a tempered glass window and a swing door. The S100 TG is cheaper and provides better component visibility, while the Define Mini C is quieter and more premium-feeling. Cooler Master MasterBox Q300L An even smaller Micro ATX case with a magnetic mesh front panel. The Q300L is lighter and has more airflow customization, but the S100 TG feels more solid with its glass panel and steel construction. The swing door is a unique convenience feature the Q300L lacks.

Things to Consider

The S100 TG only supports Micro ATX and Mini-ITX motherboards. If you plan to use an ATX board, look for a mid-tower case. Cable management space is limited. A modular PSU and careful routing are recommended to keep the interior clean. Maximum GPU length is around 320mm (with front HDD cage removed). If you have a longer GPU, check compatibility before purchasing. The swing door opens to the left, so ensure you have enough clearance on that side when placing the case. * Only 120mm fans are supported; 140mm fans will not fit. ## FAQ Q: Can I install an ATX power supply in this case? A: Yes, a standard ATX PSU fits in the rear mount. Units up to 160mm depth are recommended for comfortable cable management. Q: What size radiators fit? A: You can install a 240mm radiator in the front or top. The rear only supports a 120mm fan (no radiator). Q: Does the case come with fans? A: Yes, one 120mm fan is included pre-installed in the rear exhaust position. Additional fans are sold separately.
