Silverstone Technology Mini-DTX, Mini-ITX Small Form Factor Computer Case SG13WB Black/White

AI Verdict
The SG13 is an 11.5-liter shoebox case that fits standard ATX power supplies, built strictly for patient minimalists who want a tiny footprint without buying specialized SFX components.
The 11.5-liter chassis demands a strict assembly order and specific component choices. Dropping in an ATX power supply chokes CPU air cooler clearance to 61mm, forcing most builders to rely on a 120mm AIO liquid cooler.
If you plan to use a high-end CPU, get an SFX power supply and the adapter bracket to increase your cooler clearance and cable routing space.

Chance this product isn't for you
Pros
- Fits standard ATX power supplies up to 150mm, allowing you to reuse existing parts.
- Swallows 10.5-inch graphics cards, easily clearing dual-fan GPUs like the RTX 3060 Twin Edge.
- Front fan mount accepts a 120mm or 140mm All-in-One liquid cooler to bypass the cramped CPU socket area.
- Top drive bracket holds a full-size 3.5-inch hard drive or two 2.5-inch SSDs.
Cons
- Using an ATX power supply restricts CPU air cooler height to just 61mm.
- The front panel USB 3.0 cable is incredibly stiff and refuses to bend around tight motherboard corners.
- The single-piece top and side steel cover is flimsy and warps easily when removed.
- Zero dedicated cable routing channels or tie-down points behind the motherboard tray.
Dimension Scores
The mesh front panel allows direct intake for a 120mm AIO, but the ATX PSU placement traps heat directly over the motherboard.
The heavily vented top and side panels let all internal pump and fan noise escape directly into your room.
The internal steel frame holds components securely, but the single-piece wrap-around outer cover is thin and warps easily.
Zero space exists behind the motherboard tray, forcing you to stuff all excess cables between the front intake fan and the power supply.
Best For
- First-time small form factor builders reusing an older 140mm ATX power supply.
- Living room home theater PCs sitting on a TV console shelf.
- Backpack-sized portable gaming rigs utilizing a 120mm AIO liquid cooler.
Not Recommended For
- Builds requiring massive triple-fan graphics cards over 266mm long.
- Air-cooled setups using tall tower heatsinks.
Watch Out For
- ATX power supplies block the CPU socket — you must install your RAM, CPU, and front panel cables before dropping the PSU in.
- The top drive caddy blocks 140mm front fans — if you want to use a 3.5-inch hard drive, you are restricted to a 120mm front intake.
- No SFX power supply adapter is included in the box — you need to source Silverstone's specific bracket separately if you want to use a smaller PSU.
- Thick 90-degree SATA cables hit the top panel — the drives mount upside down, forcing you to use flat SATA connectors.

What Buyers Say
The SG13 forces builders to treat PC assembly like a puzzle box. The most recurring frustration is the incredibly stiff USB 3.0 front panel cable, which actively fights against tight bends near the motherboard. Builders consistently recommend installing the power supply absolutely last, as it completely blocks access to the CPU and motherboard headers. Despite the cramped quarters, owners love fitting standard ATX power supplies and 266mm dual-fan GPUs inside an 11.5-liter footprint.
“i literally had to take the entire power supply out just to plug in the cpu fan header, my hands are bleeding but it looks so cute on my desk.”
Common Praise
- Fits perfectly on a 20cm high TV console shelf.
- Accepts standard 140mm ATX power supplies without modification.
- Front mesh panel provides direct airflow to a 120mm AIO radiator.
- Internal steel frame feels surprisingly heavy and rigid.
Common Complaints
- The wrap-around top and side panel rarely lines up perfectly when sliding it back on.
- Front panel USB 3.0 cable is thick, stiff, and nearly impossible to route cleanly.
- ATX power supplies leave just 61mm of breathing room for CPU air coolers.
- Plastic push-pins on the front panel snap off easily if forced.
Ownership Tips
- Dust builds up quickly on the front mesh and requires wiping down weekly.
- Flipping the ATX power supply fan to face upwards exhausts hot air better but increases noise.
- The power button LED is blindingly bright in a dark room.
Frequently Asked Questions
Can I fit a 3-fan GPU in this case?
No. The maximum GPU length is 10.5 inches (266mm). You are limited to dual-fan or blower-style cards.
Does a standard ATX power supply actually fit?
Yes, it supports ATX PSUs up to 150mm long. A 140mm fully modular unit is highly recommended to leave room for cable management.
Should I use an air cooler or liquid cooling?
Liquid cooling is drastically better here. An ATX power supply sits directly over the motherboard, limiting air coolers to 61mm and starving them of fresh air.
Where do the hard drives go?
There is a bracket at the top that holds one 3.5-inch drive or two 2.5-inch drives, plus one additional 2.5-inch mount on the floor of the case.
Can I mount a 140mm fan in the front?
Yes, but installing a 140mm fan or radiator forces you to remove the top drive caddy, eliminating your 3.5-inch hard drive support.
Buying Guide
Building in an 11.5-liter case means you lose the luxury of doing things out of order. You must plan your cable routing before screwing down a single part. Using a standard ATX power supply is convenient but creates a massive headache for cable management and CPU cooling. Get a fully modular power supply and a 120mm AIO liquid cooler to save your sanity.
11.5 Liter Volume
This is the physical footprint of the case. Think of it as the size of a large shoebox, meaning it fits on a desk corner but requires extreme patience to build inside.
61mm CPU Cooler Clearance
This is the maximum height for a fan sitting on your processor. It is shorter than a credit card, which is why liquid cooling is practically mandatory with an ATX power supply.
10.5-inch (266mm) GPU Clearance
This dictates what graphics cards fit. Most modern triple-fan cards are too long, so you must shop specifically for dual-fan or 'Mini' variants.
Alternatives
If you want better cable management and support for tall air coolers, look for a 15-to-18 liter Mini-ITX tower case. If you need to fit a massive triple-fan graphics card, search for a sandwich-style ITX case with a PCIe riser cable.
