AI Verdict
The SG13 is an 11.5-liter shoebox that fits full-size ATX power supplies and 10.5-inch GPUs, making it a dirt-cheap entry point for first-time small form factor builders.
This case is a packaging marvel for $60, but the solid front panel on this 'Q' version severely limits thermal headroom. It works brilliantly if you pair a 65W CPU with a 120mm AIO liquid cooler, but air-cooled high-end chips will thermal throttle.
If you want to use a standard air cooler, buy the mesh-front version of the SG13 instead, or upgrade to a Cooler Master NR200 for better airflow.

Pros
- Fits standard ATX power supplies up to 150mm long, saving you $50 over buying an SFX unit
- Swallows 10.5-inch dual-slot GPUs like the RTX 3060 without requiring a PCIe riser cable
- Supports a 120mm or 140mm All-In-One liquid cooler right behind the front panel
- At just 11.5 liters in volume, it takes up less desk space than a standard piece of printer paper
Cons
- The solid front panel on this specific 'Q' model chokes airflow compared to the mesh version, pushing CPU temps into the 80s on air cooling
- Using an ATX power supply limits your CPU air cooler height to a microscopic 61mm
- Zero cable routing channels or tie-down points force you to shove excess PSU cables directly above the motherboard
- The outer shell is made of thin steel that easily bends if you force the panels back on
Dimension Scores
Packs a full ATX PSU, 10.5-inch GPU, and 120mm AIO into an 11.5-liter footprint.
The solid front panel blocks noise slightly, but forces fans to spin at 3000+ RPM to compensate for trapped heat.
The internal chassis and outer shell use thin steel that flexes easily, and the plastic front panel tabs are brittle.
There are literally zero routing channels; you just stuff excess cables into the gap between the front fan and the motherboard.
Best For
- Budget SFF builders reusing an old 150mm ATX power supply and 2.5-inch SSDs
- Living room HTPC setups where the 11.5L footprint fits perfectly inside a TV console shelf
- 1080p gaming rigs using a 120mm AIO liquid cooler and a dual-fan 10.5-inch GPU
Not Recommended For
- High-TDP processors like the Ryzen 9 or Core i9 that require massive dual-tower air coolers
- Anyone using a triple-fan graphics card longer than 270mm
Watch Out For
- The solid front panel traps heat—if you use a stock 61mm air cooler instead of a 120mm AIO, expect your CPU to hit 85°C under load.
- If you use an ATX power supply, you literally have to plug in all your cables before dropping it in, because it sits directly over the motherboard with zero hand clearance.
- The SFX power supply adapter bracket isn't included in the box, so you have to buy the PP08B separately if you want 82mm of CPU cooler clearance.
- The front I/O cables are obnoxiously long for an 11.5L case and will sit directly on top of your RAM or GPU backplate.

What Buyers Say
The SG13's 11.5-liter volume forces a specific build order, starting with the motherboard and ending with the power supply hovering millimeters above the CPU. The solid front panel on this specific model creates a hotbox effect, making a 120mm AIO liquid cooler practically mandatory to keep CPU temps under 80°C. Forum threads are filled with warnings that while it fits an ATX power supply, the resulting cable nest blocks airflow so badly that buying an SFX unit is worth the extra cost. Despite the cramped quarters, it remains a favorite for budget HTPC builds because it swallows standard 10.5-inch GPUs without requiring an expensive PCIe riser cable.
“I crammed an ATX psu and a 1660 super in here and it works but my god the cables are a nightmare and the solid front panel makes it an absolute oven if you don't use an AIO.”
Common Praise
- Fits standard 10.5-inch GPUs without needing a PCIe riser cable
- ATX power supply support saves budget builders from the SFX tax
- 11.5-liter footprint easily fits inside standard IKEA TV console shelves
- Front bracket natively supports 120mm AIO radiators for direct CPU cooling
Common Complaints
- Solid front panel chokes intake air, causing 10-15°C higher temps than the mesh version
- Zero cable management space means wires rest directly on the GPU backplate
- Outer steel shell is paper-thin and the side panels rarely align perfectly on the first try
- Removing the motherboard requires taking out the power supply and GPU first
Ownership Tips
- The plastic tabs holding the front panel snap off easily if you remove it too many times to clean the dust filter.
- Flipping the ATX power supply fan to face downward helps exhaust CPU heat, acting as a secondary case fan.
- You will need to buy a custom short cable kit if you want any semblance of airflow inside the chassis.
Frequently Asked Questions
Can I fit a standard ATX power supply in this?
Yes, it fits ATX PSUs up to 150mm long. Just know it will sit directly over the motherboard, restricting your CPU cooler height to 61mm.
Will a 3-fan GPU fit?
No. The absolute maximum GPU length is 10.5 inches (270mm), which restricts you to dual-fan or blower-style cards.
Do I need an AIO liquid cooler?
For this solid-front model, a 120mm AIO is highly recommended. Users report air coolers easily hitting 85°C because the ATX power supply blocks exhaust paths.
Where do the hard drives go?
You can mount one 3.5-inch drive or two 2.5-inch SSDs on a removable bracket at the top of the case. You have to remove this bracket if you use a tall CPU cooler.
Does it come with any case fans?
No fans are included in the box. You must buy your own 120mm or 140mm fan for the front intake.
Buying Guide
When building in an 11.5-liter case, the order of operations is everything. You cannot drop your power supply in until every single motherboard cable, front panel header, and RAM stick is seated. Because this specific model has a solid plastic front panel instead of mesh, you are severely restricting intake air. You must use a 120mm AIO liquid cooler pushing air out the front, or your system will thermal throttle during gaming.
11.5L Volume
This is the physical footprint of the case. At 11.5 liters, it's about the size of a large shoebox, taking up half the desk space of a standard mid-tower.
150mm ATX PSU Clearance
It dictates the physical size of the power box you can use. Standard ATX fits, but it sits directly over the motherboard like a low ceiling, restricting your CPU cooler to just 61mm tall.
10.5-inch GPU Maximum
This is the hard limit for your graphics card length. Anything over 270mm will physically hit the inside of the front panel and won't fit.
Alternatives
If you want to use a tall air cooler or a triple-fan GPU, look for an 18-liter ITX case with a mesh front panel and vertical GPU mounting.
