AI Verdict
The SilverStone SG13 is an ultra-compact 11.5L ITX case perfect for builders who want a console-sized footprint and are willing to wrestle with tight cable management.
The SG13 is a brilliant space-saver if you carefully plan your component dimensions, specifically sticking to a 120mm AIO and a strict 2-slot GPU. The 11.5L volume and lack of dedicated cable routing channels make it a frustrating puzzle if you try to cram in a full-size ATX power supply and a 3.5-inch hard drive.
If you want to use a modern 2.5-slot or 3-slot GPU, upgrade to a slightly larger case in the 18-20L range.

Chance this product isn't for you
Pros
- Fits standard ATX power supplies up to 150mm, saving you the SFX premium on components
- Supports 120mm or 140mm AIO liquid coolers in the front panel
- Accommodates 10.5-inch (270mm) graphics cards despite the tiny 11.5-liter volume
- Elevated motherboard standoffs create a 5mm channel for routing thin cables underneath
Cons
- Strict 61mm CPU cooler height limit practically forces you to use an AIO or low-profile cooler
- Using an ATX power supply leaves almost zero room for the thick 24-pin motherboard cable
- The solid plastic front panel on the 'Q' version restricts intake airflow compared to the mesh variant
- Strictly limited to true 2-slot GPUs (129mm width max), ruling out most modern high-end cards
Dimension Scores
Fits a 270mm GPU and an ATX power supply into an 11.5-liter footprint, though the solid front panel restricts thermal efficiency.
The heavily ventilated side and top panels let component noise escape easily, especially when fans ramp up to compensate for the solid front panel.
The steel frame is sturdy enough, but the faux aluminum plastic front panel feels cheap and the side panels require force to align.
Zero dedicated routing channels force you to stuff excess cables into the tiny gap above the GPU.
Best For
- Budget SFF builds reusing an older ATX power supply
- Living room HTPC setups that need to fit inside a standard TV console cabinet
- Backpack-friendly portable gaming rigs for LAN parties
Not Recommended For
- First-time PC builders who want an easy, frustration-free cable routing experience
- High-end builds using 2.5-slot or 3-slot graphics cards
Watch Out For
- ATX PSU trap — while standard ATX power supplies fit, anything longer than 140mm crushes your cables against the front fan.
- The 140mm AIO catch — installing a 140mm radiator forces you to remove the upper drive cage and shrinks your max GPU length to 236mm minus the radiator thickness.
- Air cooling suffocation — the power supply mounts directly over the motherboard, severely choking the airflow of any low-profile air cooler you install.
- Strict 2-slot GPU limit — if your graphics card is even a few millimeters wider than a true 2-slot (129mm), the side panel simply will not close.

What Buyers Say
Building in the SilverStone SG13 demands serious patience. While an ATX power supply technically fits, real-world builds show it turns cable management into a nightmare and chokes CPU air coolers. Pairing this case with a 120mm AIO and an SFX power supply transforms it from a frustrating puzzle into a brilliant 11.5L powerhouse. The 'Q' version's solid front panel looks cleaner than the mesh variant, but the plastic shield noticeably increases internal temperatures.
“I love how tiny this thing is on my desk, but trying to shove a non-modular ATX power supply and its cables in here made me want to pull my hair out.”
Common Praise
- Incredible 11.5-liter size fits perfectly on small desks or inside TV cabinets
- Accepts standard ATX power supplies, keeping budget builds cheap
- Fits a 120mm AIO liquid cooler natively on the front intake
- Top and side panels are heavily ventilated to help exhaust hot air
Common Complaints
- The 24-pin ATX cable is incredibly difficult to route without blocking the front fan
- Side panels often do not line up perfectly when sliding them back into place
- Solid plastic front panel on the Q-variant restricts intake airflow
- Zero clearance for graphics cards wider than a strict 2-slot (129mm)
Ownership Tips
- Dust builds up quickly through the top and side vents since there are no magnetic filters included.
- You will likely need to buy a custom short cable kit or an SFX power supply if you want to use a 3.5-inch hard drive.
- The front panel audio and USB cables are excessively long and require creative zip-tying to hide.
Frequently Asked Questions
Can I use an ATX power supply?
Yes, it supports ATX PSUs up to 150mm long. Using an SFX power supply with an adapter bracket is highly recommended to free up breathing room and cable space.
Should I use an air cooler or an AIO liquid cooler?
An AIO liquid cooler is strongly recommended. The power supply sits directly above the CPU, limiting air coolers to 61mm and starving them of fresh air.
Will a 3-fan graphics card fit?
It depends entirely on the length and width. The absolute maximum limits are 270mm (10.6 inches) long and 129mm (5.11 inches) wide, ruling out most modern 3-fan cards.
Where do I hide the extra cables?
There is a small pocket of dead space above the GPU and between the front fan and the power supply. You will need plenty of zip ties to keep cables out of the front intake fan.
Does the 'Q' version have worse temperatures?
Yes, the SG13WB-Q features a solid plastic front panel with a faux aluminum finish. This restricts intake airflow compared to the standard mesh front versions.
Buying Guide
Building in an 11.5-liter case is a game of millimeters. You cannot just buy parts and hope they fit — you must check the exact length and width of your GPU, and the exact length of your power supply. While the SG13 advertises ATX power supply support, doing so makes your build significantly harder and hotter. Do yourself a favor and buy an SFX power supply with an ATX adapter bracket, and use a 120mm AIO liquid cooler instead of a low-profile air cooler.
11.5 Liters Volume
This is the physical footprint of the case. For context, a standard mid-tower PC is around 40 to 50 liters, making this about the size of a large shoebox.
150mm PSU Limit
This dictates how long your power supply can be. If you buy a 160mm unit, it will physically crash into the back of your front intake fan.
61mm CPU Cooler Clearance
Because the power supply mounts directly over the motherboard, a standard tower cooler will not fit. You must use a pancake-style low-profile cooler or a liquid cooler.
Alternatives
If you want to use a larger 3-slot graphics card or a tall tower air cooler, look for an ITX case in the 18-20 liter range with a traditional layout.
