AI Verdict
The SilverStone SG13 is an 11.5-liter shoebox-sized ITX case built for SFF builders who want to reuse standard ATX power supplies and 10.5-inch dual-fan GPUs.
The 11.5-liter volume is incredibly space-efficient, but cramming an ATX power supply directly over the motherboard chokes air coolers taller than 61mm. You must use a 120mm AIO liquid cooler to keep CPU temperatures manageable under gaming loads.
Buy an SFX power supply and the SilverStone PP08 adapter bracket to increase CPU cooler clearance to 82mm.

Pros
- Fits standard ATX power supplies up to 150mm, allowing reuse of older components
- Mesh front panel allows a 120mm or 140mm AIO liquid cooler to pull fresh room air directly over the motherboard
- Supports 10.5-inch dual-slot graphics cards, easily fitting twin-fan models like the Zotac 1660 Super
- Elevated motherboard standoffs provide extra clearance for rear-mounted M.2 SSDs to breathe
Cons
- Using an ATX power supply limits CPU cooler height to 61mm, forcing reliance on an AIO or a low-profile cooler like the Noctua L9i
- Top 2.5-inch drive bracket blocks cable routing and airflow when paired with a 140mm length ATX power supply
- Front panel USB 3.0 cables are excessively long for an 11.5L case, creating a rat's nest near the GPU
- Side panels frequently misalign during reattachment, leaving a tiny gap near the front plastic bezel
Dimension Scores
Fits a 10.5-inch GPU and a 120mm AIO in just 11.5 liters of desk space.
The mesh front panel lets sound escape easily, and the cramped interior forces fans to spin faster to maintain temps.
The steel frame is flimsy when the panels are off, and the side panels frequently misalign during reassembly.
There is zero space behind the motherboard tray, forcing you to stuff excess cables between the front fan and the GPU.
Best For
- Living room TV console gaming rigs where the 11.5L footprint blends in like a subwoofer
- First-time small form factor builders reusing an old ATX power supply and a dual-fan GPU
- Backpack-sized portable setups for college dorms or LAN parties
Not Recommended For
- High-TDP processors like the Core i9 or Ryzen 9 that require massive dual-tower air coolers or 240mm radiators
- Builds using triple-fan graphics cards longer than 266mm
- Showcase builds, as the side panels are solid steel with ventilation cutouts instead of tempered glass
Watch Out For
- Installing the power supply first makes it physically impossible to route the front panel cables or mount the motherboard
- Using a 140mm front intake fan severely cuts into your GPU length clearance, often blocking cards longer than 9 inches
- The top drive caddy only fits 3.5-inch hard drives if they are full-height; thinner drives lack the correct side screw hole alignment
- 90-degree SATA cables hit the top panel because the 2.5-inch drives mount upside down on the bracket

What Buyers Say
The most critical detail builders discover is the strict installation order—if you mount the power supply before the motherboard and front panel cables, you have to take everything apart. The ability to use a standard ATX power supply is a massive draw, but it sits directly over the motherboard, restricting CPU air coolers to a mere 61mm in height. Because of this, nearly everyone ends up buying a 120mm AIO liquid cooler and mounting it to the front mesh panel. Cable management is non-existent, requiring builders to shove excess wires into the small gap next to the front intake fan.
“I love the shoebox size but trying to cram my non-modular ATX power supply cables next to the AIO tubes literally made my fingers bleed, just buy an SFX power supply and save your sanity.”
Common Praise
- Fits perfectly inside a standard 20cm high TV console shelf
- Front mesh panel allows a 120mm AIO to pull fresh room air directly through the radiator
- Accepts standard ATX power supplies up to 150mm
- Elevated motherboard standoffs prevent rear-mounted M.2 SSDs from overheating against the bottom panel
Common Complaints
- ATX power supplies block the top 2.5-inch SSD mount and choke downdraft CPU air coolers
- Side panels require bending and wiggling to line up the rear screw holes
- Front panel USB 3.0 cables are stiff and far too long for the 11.5L interior
- 90-degree SATA cables hit the top panel because the drive bracket mounts drives upside down
Ownership Tips
- Dust builds up quickly on the front mesh, requiring a wipe-down every two weeks to maintain airflow
- The front 120mm fan filter is removable, but you have to pop off the entire plastic front bezel to access it
- Blower-style GPUs actually perform better here than open-air cards because they exhaust heat out the back instead of dumping it into the unvented bottom chassis
Frequently Asked Questions
Can I fit an ATX power supply and a 120mm AIO cooler at the same time?
Yes, but you need to route the AIO tubes carefully around the RAM before screwing in the power supply. A 140mm ATX PSU leaves just enough room for the tubes to bend.
Does a 3.5-inch hard drive fit?
Yes, the top bracket holds one 3.5-inch drive, but it blocks the top ventilation and makes cable management extremely tight.
Will a 3-fan GPU fit?
No. The absolute maximum GPU length is 10.5 inches (266mm), which restricts you to dual-fan or blower-style cards.
Should I mount the power supply fan facing up or down?
Mount it facing up to pull fresh air through the top case vent. Facing it down forces the PSU to swallow hot air directly from the CPU area.
Do I need a modular power supply?
You absolutely want one. Stashing unused Molex and SATA cables in an 11.5L chassis blocks the front intake fan and chokes the GPU.
Buying Guide
You are building in an 11.5-liter box, which means the order you install parts dictates whether the build succeeds or fails. You must install the motherboard, front panel connections, and AIO cooler before even looking at the power supply. While the spec sheet says ATX power supplies fit, buying a smaller SFX unit gives you crucial breathing room for cable routing. Skip the 3.5-inch hard drive entirely, as the mounting bracket blocks the only exhaust path at the top of the case.
11.5 Liters Volume
Think of this as the total cubic space inside the case. At 11.5L, it's roughly the size of a large shoebox, meaning every single cable and component will touch each other.
10.5-inch GPU Clearance
This dictates the physical length of the graphics card you can buy. You are restricted to dual-fan models, as modern triple-fan cards will physically hit the front metal frame.
61mm CPU Cooler Height
This is the gap between your processor and the power supply above it. It's so narrow that standard air coolers will suffocate, making a liquid cooler almost mandatory.
Alternatives
If you want to use a massive triple-fan graphics card or a tall tower air cooler, look for a 15-18 liter ITX case with a sandwich-style layout or a vertical tower design.
