AI Verdict
The SG13B-Q is an 11.5-liter shoebox case that fits full-sized parts on a tight budget, perfect for first-time small form factor builders who want a stealthy living room PC.
The SG13B-Q crams impressive hardware compatibility into 11.5 liters, but the solid front panel traps heat. You have to carefully plan your build around a 120mm AIO liquid cooler and an SFX power supply to keep temperatures under control.
If you are running a CPU hotter than a Ryzen 5 or Core i5, buy the mesh-front SG13 version instead for better intake airflow.

Pros
- 11.5-liter footprint takes up barely any space on a desk corner or TV stand
- Fits standard 10.5-inch dual-fan graphics cards without requiring a PCIe riser cable
- Supports a 120mm or 140mm All-in-One liquid cooler right behind the front panel
- Accepts standard ATX power supplies to save money on expensive SFX units
Cons
- Solid faux-aluminum front panel chokes intake airflow compared to the mesh SG13 version
- ATX power supplies sit directly over the motherboard, limiting CPU air coolers to a tiny 61mm height
- Zero included case fans — you have to buy your own 120mm or 140mm intake fan
- The single-piece U-shaped outer shell is notoriously frustrating to slide back into place and often leaves a small gap
Dimension Scores
Fits a 10.5-inch GPU and 140mm AIO in just 11.5 liters, but the solid front panel restricts thermal headroom.
The solid front panel blocks coil whine and fan noise better than the mesh version, provided your fans don't ramp up to 100%.
The steel frame is sturdy, but the U-shaped outer shell feels flimsy and rarely lines up perfectly on the first try.
There is zero space behind the motherboard tray; excess cables just get shoved above the front intake fan.
Best For
- Budget 1080p living room HTPC builds using mid-range, low-heat components
- First-time small form factor builders migrating older ATX power supplies and 2.5-inch SSDs
- Dorm room desks where an 11.5L footprint is the absolute maximum allowed
Not Recommended For
- High-end gaming rigs pushing 300W+ GPUs that need massive airflow
- Builders who want to use tall tower air coolers like the Noctua NH-D15
Watch Out For
- Using an ATX power supply crushes your cable management space and forces you to use a low-profile CPU cooler under 61mm
- The 3.5-inch hard drive bracket blocks the top vents and makes routing thick 24-pin motherboard cables a nightmare
- You need to buy an SFX to ATX adapter bracket separately if you want to use a smaller, more manageable SFX power supply
- Using 90-degree SATA cables on a 3.5-inch drive prevents the top case panel from closing

What Buyers Say
The SG13 is a legendary entry-level ITX case, but the solid-front 'Q' version requires careful planning. The 11.5-liter footprint is incredibly desk-friendly, and the ability to reuse a standard ATX power supply saves money. Cable management is practically non-existent, forcing builders to shove excess wires into the top drive caddy area. Thermals are the biggest hurdle; the power supply sits directly over the motherboard, meaning a 120mm AIO liquid cooler is almost mandatory to keep the CPU from throttling.
“I crammed an ATX power supply in here to save money and instantly regretted it when I had to bend the 24-pin cable at a 90-degree angle just to close the lid.”
Common Praise
- 11.5-liter size fits perfectly inside IKEA Kallax shelves and tight TV cabinets
- Standard 10.5-inch GPU support means you don't have to buy expensive low-profile graphics cards
- Motherboard standoffs are elevated, allowing M.2 SSDs to be mounted on the back of the board without shorting
- Steel chassis feels surprisingly heavy and rigid for a $50 case
Common Complaints
- The U-shaped outer cover bends easily and the screw holes rarely align perfectly when closing the case
- Using a full-size ATX power supply makes routing the thick 24-pin cable nearly impossible
- Solid faux-aluminum front panel starves the front intake fan of fresh air
- Front panel USB 3.0 cables are way too long and clutter the tiny interior
Ownership Tips
- Flipping the power supply fan to face upwards acts as a secondary exhaust and drops case temps by a few degrees
- The faux-aluminum plastic front panel scratches easily if you wipe it with a rough microfiber cloth
- Dust builds up quickly on the side vents because the front intake is so restricted
Frequently Asked Questions
Can I fit a standard ATX power supply in this case?
Yes, it physically fits. But it sits directly above the motherboard, leaving you with just 61mm of clearance for a CPU cooler and zero room to hide extra cables.
Does it come with any case fans?
No. You must buy your own 120mm or 140mm fan for the front intake to keep your parts from cooking.
Will my 3-fan graphics card fit?
Probably not. The absolute maximum GPU length is 10.5 inches (266mm). Measure your card before buying, as most modern 3-fan cards exceed 300mm.
Should I use an air cooler or liquid cooler?
A 120mm All-in-One liquid cooler mounted to the front is highly recommended. Tower air coolers simply will not fit under the power supply.
Is the front panel real aluminum?
No, the 'Q' in SG13B-Q stands for Quiet, and it uses a solid plastic front panel with a faux brushed-aluminum finish.
Buying Guide
Building in an 11.5-liter case means the order of installation is critical. You cannot plug in motherboard headers once the power supply is screwed in. While the spec sheet says ATX power supplies fit, buying an SFX power supply and a $10 adapter bracket will save you hours of frustration. Skip the 3.5-inch hard drives entirely; use M.2 or 2.5-inch SSDs to keep the airflow path clear.
11.5 Liters Volume
Think of this as the size of a large shoebox. It dictates exactly how much desk space you lose, but also means every millimeter inside counts.
61mm CPU Cooler Clearance
This is the tiny gap between your processor and the power supply. Standard coolers won't fit, forcing you to buy a specialized low-profile fan or a liquid cooler.
10.5-inch (266mm) GPU Length
This is the hard limit for your graphics card. If you buy a massive three-fan GPU, it will physically stick out the front of the metal frame.
Alternatives
If you want better temperatures, search for the mesh-front version of this exact case. If you want an easier build process with better cable routing, look for an 18-liter ITX case.
