AI Verdict
This 11.5-liter shoebox is a cheap, space-saving dream for budget 1080p builds, but the strict 10.5-inch GPU limit and zero cable management will punish first-time builders.
At 11.5 liters, it packs incredible space efficiency for the price, but the strict 10.5-inch, 2-slot GPU limit rules out most current-gen graphics cards. It thrives as a budget 1080p rig or HTPC, provided you use a 120mm AIO liquid cooler to overcome the cramped internal layout.
If you want to run a modern 3-slot GPU or a tall tower air cooler, step up to a 15-18L case.

Pros
- Shrinks your PC down to an 11.5-liter shoebox footprint for under $60
- Mesh front panel feeds direct fresh air to a 120mm or 140mm AIO radiator
- Fits standard 3.5-inch hard drives on a top-mounted bracket
- Ventilated side panels allow 2-slot GPUs to pull cold air straight from the room
Cons
- ATX power supplies sit directly over the motherboard, choking CPU air coolers to a 61mm height limit
- Zero cable routing channels or tie-down points anywhere in the chassis
- Strict 10.5-inch length and 2-slot thickness limit rules out most modern high-end GPUs
- Front panel uses brittle plastic retention clips that snap easily
Dimension Scores
A 120mm AIO works great, but air cooling is severely choked by the PSU placement.
The mesh front lets noise escape easily, and cramped fans have to spin faster to keep temps down.
The steel frame is thin and flexes when panels are off, though it feels solid once fully assembled.
There are zero routing channels, no tie-downs, and excess cables just get shoved above the motherboard.
Best For
- Budget 1080p gaming builds using a 120mm AIO liquid cooler
- Living room HTPCs that need to slide into a tight TV console shelf
- Backpack-portable LAN rigs using mid-range, low-TDP hardware
Not Recommended For
- Modern 3-slot graphics cards like the RTX 4070 Ti or higher
- First-time builders who want an easy, forgiving cable management experience
Watch Out For
- Using an ATX power supply leaves only 61mm of CPU cooler clearance and chokes airflow — you really need an SFX PSU and a $15 adapter bracket.
- The power supply must be installed absolutely last, or you won't be able to plug in motherboard cables or route the AIO tubes.
- The top 3.5-inch drive tray blocks cable routing and interferes with larger power supplies, forcing most people to remove it entirely.
- No case fans are included in the box, so you have to buy a 120mm intake fan or rely on an AIO cooler's fan.

What Buyers Say
The SG13 is a legendary budget SFF case, but its age shows the second you try fitting modern components inside. Builders universally agree that while the spec sheet claims ATX power supply support, actually using one turns the interior into a frustrating, cable-stuffed oven. The mesh front panel does a surprisingly good job feeding a 120mm AIO liquid cooler, which the community insists is the only way to cool this thing properly. Cable management is literally non-existent, forcing a strict order of operations where the power supply must be installed absolutely last.
“I love the size and the price, but trying to cram a non-modular ATX power supply into this tiny shoebox almost made me throw it out the window.”
Common Praise
- Incredible footprint-to-hardware ratio at just 11.5 liters
- Mesh front panel allows a 120mm AIO to keep mid-range CPUs surprisingly cool
- Fits perfectly in standard IKEA Kallax shelves and TV console units
- Price point is unbeatable for a true Mini-ITX form factor
Common Complaints
- ATX power supplies choke the CPU cooler and leave nowhere to hide cables
- Zero cable routing channels or tie-down points behind the motherboard
- Strict 2-slot, 266mm GPU limit makes finding modern graphics cards difficult
- Front panel uses brittle plastic retention clips that snap easily
Ownership Tips
- Dust builds up quickly on the front mesh if you run the front fan as an intake, requiring weekly wipe-downs.
- You will likely end up removing the top drive caddy entirely just to give the cables some breathing room.
- Flipping the power supply fan to face upwards helps exhaust hot air, but makes the PSU run noticeably louder.
Frequently Asked Questions
Can I actually use an ATX power supply?
Yes, up to 150mm long, but it sits directly over the motherboard and restricts CPU coolers to 61mm. Most builders highly recommend buying an SFX power supply and a $15 adapter bracket to increase cooler clearance to 82mm.
Will a 3-slot GPU fit?
No. The case strictly supports 2-slot graphics cards up to 10.5 inches (266mm) in length. Anything thicker will prevent the outer shell from closing.
What is the best way to cool the CPU?
A 120mm All-In-One (AIO) liquid cooler mounted to the front mesh panel as an intake. Air coolers struggle because the power supply blocks the exhaust path.
Does it come with any case fans?
No. You need to buy your own 120mm or 140mm front fan, or use the fan that comes with your AIO liquid cooler.
Can I fit a 3.5-inch hard drive?
Yes, there is a top mounting bracket for one 3.5-inch drive. Just know that using it makes cable management significantly harder and can block taller CPU coolers.
Buying Guide
Building in an 11.5-liter case requires planning every single component before you buy. You can't just throw spare parts in here and expect them to fit or stay cool. Liquid cooling is practically mandatory because the power supply sits directly above the CPU, blocking traditional air coolers. You also need to measure your graphics card down to the millimeter, as anything thicker than a standard 2-slot design simply won't let the outer shell slide shut.
11.5 Liter Volume
This is the physical footprint of the case. At 11.5L, it's about the size of a large shoebox, taking up minimal desk space compared to a standard 40L mid-tower.
61mm CPU Cooler Clearance
This is the maximum height for a fan sitting on your processor. 61mm is extremely restrictive, which is why builders use liquid coolers that move the bulky radiator to the front of the case.
10.5-inch (266mm) GPU Length
If your graphics card is 267mm long, it will hit the front metal frame. You must check your GPU's exact dimensions before buying.
Alternatives
If you want to use a modern 3-slot graphics card or a standard ATX power supply without wanting to pull your hair out, look for a 15-18L sandwich-style ITX case.
