Compact and Elegant Design
Full metal construction with sleek front panel design, the S300 TG Mid Tower Chassis showcases its simply and elegant design.
Built-in PSU Cover and Riser GPU Bracket
The built-in PSU cover with a ventilated design can improve airflow and hide those unsightly cables. The integrated riser GPU support bracket not only prevents the graphic card from sagging, but helps reduce the weight on the motherboard PCI-E slots.
Patented Rotational PCI-E 7 Slot Design
With Patented Rotational PCI-E slots, you can choose to display your graphics cards vertically which helps you gain flexible space for your system.
Tempered Glass Window
The 4mm tempered glass window on the side of the S300 TG is built to be more durable, scratch resistant, and transparent for an advanced view of your hardware.
Dust Reduction
Two magnetic super fine fan filters with excellent protection and reduction against dirt on the top and the right side and another removable filter at the bottom.
Superior Hardware and Liquid Cooling Support
S300 TG has excellent expandability. It can support a CPU cooler with a maximum height of 170mm, dual VGA expansion slot of up to 360mm in length without a reservoir, and a power supply with a length of up to 200mm. Optimized for excellent cooling capability with one 120mm exhaust rear fan preinstalled, S300 TG is able to house up to three 140mm or two 200mm front fans, up to three 120mm fans on top, and a radiator of up to 360mm at the front to allow users to build their desired high-end system.
Handy I/O Ports
One 3.0 USB and two 2.0 USB ports on top-front panel to grant direct access when needed.

Pros: +Nice and spacious +Good thermals despite the closed off front panel. Raised for ample power supply airflow +Minimalist look, steel panelling on front +Dust filters on every almost any potential intake path (no dust filter on front panel at the bottom where you use to pull the panel off. It's just open): front panel side intakes, top magnetic filter, rear side panel magnetic filter, bottom 2 intake filters (one for power supply and the other for air holes near HDD cage. +Glass panel shows everything! Black bezels hide rolled edges. +Power supply cover shows power supply logo, but depending on the brand it may or may not be upside down if you want top intake or bottom intake orientation +Rotatable PCI bracket lets you choose if you want to mount your GPU horizontally or vertically* +Spaces for ample fan configurations (check specs for full details) +System is fairly quiet with 3x120mm fans at the front intake, 1 rear 120mm exhaust w/GPU radiator, and 240mm CPU radiator at the top. Temps at load: Ambient 31C (reported by motherboard) Ryzen 7 3700x 4.2Ghz stock 61C RTX 2080 MSI Seahawk stock 53C
Cons: -*Does not ship with the PCI riser cable. Wish there was an option to add it when purchasing the case, so they'd come together, but I guess Newegg wasn't able to, so I received the case first, built my system, then when the Thermaltake riser cable I also ordered came a week later, I was able to install without much of an issue. One thing I did notice though, was the screws used to mount the riser cable to the PCI bracket ended up being over-threaded, so now the screw just keeps spinning after a few screws. But as long as I don't move the GPU too much it shouldn't be a problem. -It says you can fit 2x200mm fans at the front, which is true, but you can only mount them on the outside of the fan mount. This becomes an issue because the fans are mere milliliters from the front panel, so airflow is severely hindered. Stuck with having 3x120mm at the front mounted on the inside producing much better airflow.
Overall Review: Overall this is a very good case! Thermaltake has been around for quite some time, and they rarely get the praise they deserve! This is the 3rd case I've owned from them, the first two being the Suppressor F31 (which was basically a Fractal Define R3) and 2nd being the smaller Core V21. Haven't had any bad experiences with Thermaltake!
