Overview
The PCCOOLER C3D310 M-ATX Mid Tower PC Case enters a crowded sub-$100 market with a distinctive triangular design and a 3mm tempered glass side panel that punches well above its price tag visually. Launched in early 2024 as part of PCCOOLER's CPS lineup, this compact gaming case measures just 220mm wide — slim enough to sit comfortably on a smaller desk without feeling cramped. At roughly the same price as the Fractal Focus G or Cooler Master NR400, the C3D310 carves out a niche by prioritizing aesthetics and build accessibility together. It won't unseat heavier, more rigid competitors on build quality alone, but the value proposition is genuinely hard to ignore.
Features & Benefits
Two pre-installed 120mm ARGB fans ship in the box, which means you get working airflow and lighting from the moment you close the side panel. That's a nice convenience, but don't expect them to carry a heavy thermal load on their own — they're a starting point. The real headline is the 280mm radiator support, which gives the C3D310 a credible upgrade path if you decide to go liquid later. GPU clearance reaches 350mm, comfortably fitting cards like the RTX 4070 or RX 7800 XT. The 165mm CPU height limit works with popular air coolers including the DeepCool AK400. The snap-on side panel, meanwhile, is a genuine time-saver during cable management.
Best For
This M-ATX enclosure is a strong fit for first-time builders who want a forgiving assembly process and a result that looks good on a desk. The tool-free panel removal genuinely helps when you're routing cables or repositioning components mid-build — a small thing that makes a real difference. Budget-focused gamers building around compact boards will appreciate how much hardware it fits without going wide. It's also a solid pick for dorm rooms or secondary rigs where desk space is limited. One underrated use case: buyers who plan to add a 240mm or 280mm AIO later but aren't ready to spend on one now. This case keeps that door open without forcing the decision.
User Feedback
Across nearly 100 ratings, the C3D310 holds a 4.3-star average, which tells a reasonable story. Owners consistently call out the tempered glass clarity as a highlight — it looks noticeably cleaner than the acrylic panels found on competing cases at this price. The snap-release panel gets specific praise for making cable management less of an ordeal. On the critical side, the 0.6mm steel chassis does feel thin when you're pressing against it during installation, and a few builders report slight flex. Tight interior clearance can also make routing modular PSU cables or thick GPU power connectors awkward. ARGB sync with third-party controllers has been hit or miss. Overall, it's a satisfying buy for most, with real caveats for experienced builders expecting more rigidity.
Pros
- Two ARGB fans are included out of the box, so you get working lighting and airflow from day one.
- The 3mm tempered glass panel offers genuinely clear visibility that looks sharp for the price.
- Snap-release side panel removal is a practical time-saver during cable management and component adjustments.
- GPU clearance reaches 350mm, fitting popular cards like the RTX 4070 and RX 7800 XT without issue.
- The 165mm CPU height limit supports widely used air coolers, including the DeepCool AK400.
- Radiator support up to 280mm gives buyers a real upgrade path to liquid cooling without switching cases.
- The slim 220mm width keeps the footprint small, which matters on a crowded desk or in a dorm room.
- At this price point, the storage options — three 2.5-inch SSD bays and two 3.5-inch HDD bays — are genuinely generous.
- The triangular design language stands out visually compared to the plain rectangles dominating this budget category.
Cons
- The 0.6mm steel chassis flexes under moderate pressure, which can feel unsettling during a first build.
- Interior clearance is tight enough that routing thick modular PSU cables becomes a frustrating puzzle.
- Only two 120mm fans ship installed, which is insufficient for high-TDP builds without adding more cooling hardware.
- ARGB sync with third-party controllers and software is inconsistent and may require manual troubleshooting.
- The four expansion slots limit future upgrades for anyone wanting to add multiple PCIe cards beyond GPU and one other device.
- PSU length is capped at 200mm, which rules out some longer fully-modular power supplies from brands like Seasonic or Corsair.
- ABS plastic accents on the exterior can feel noticeably cheaper than the metal and glass combination suggests at first glance.
- Cable management space behind the motherboard tray is limited, making a clean build harder than expected for beginners.

Suitable for:
The PCCOOLER C3D310 M-ATX Mid Tower PC Case is genuinely well-suited for first-time builders who want a low-stress assembly experience without sacrificing visual appeal. The snap-on side panel and straightforward interior layout mean you spend less time wrestling with the case and more time actually building. Gamers on a tight budget who want ARGB lighting out of the box will find real value here, since most competing cases at this price ship without any fans at all. The slim 220mm width makes it a practical pick for compact desk setups, dorm rooms, or secondary rigs where physical footprint actually matters. It also makes sense for anyone planning to add a 240mm or 280mm AIO cooler down the line, since the case supports it without requiring an upgrade — you can grow into it at your own pace.
Not suitable for:
Experienced builders with high-performance hardware should think carefully before committing to this M-ATX enclosure. The 0.6mm SPCC steel body is honest entry-level construction — it gets the job done, but it flexes noticeably under pressure and lacks the solid, confidence-inspiring feel of cases from Fractal Design or Lian Li at higher price points. Anyone running a high-TDP CPU alongside a power-hungry GPU will likely need to add fans immediately, since two 120mm units are not enough to keep thermals in check under sustained load. The limited interior clearance can become a real headache if you're using a modular PSU with thick sleeved cables or a wide GPU with dual 8-pin connectors — routing gets tight fast. Users who want full ARGB ecosystem sync through non-PCCOOLER software or controllers may also run into compatibility friction that requires workarounds.
