What impressed me most during unboxing was the inclusion of three 140mm fans as standard – many competitors at this price point only include two 120mm fans. However, as I discovered during testing, these fans are both a blessing and a curse.
Exterior Design & First Impressions
Quick Answer: The PM01 features an aggressive, angular design with a focus on maximum airflow through its distinctive front panel mesh configuration.
The Primera PM01 makes a bold statement with its angular, aggressive styling that won’t appeal to everyone. The front panel features distinctive arrow-shaped mesh sections that channel air directly to internal components.
Build quality exceeded my expectations at this price point. The steel construction feels solid with minimal flex, and panel gaps are consistently tight. The case weighs 8.1kg empty, providing stability during builds.

The front I/O placement on the top-front edge proves convenient for desktop placement. During my 45-day test period, I appreciated the easy access to USB ports and the tactile feedback of the power and reset buttons.
One design choice that divided opinions among colleagues was the prominent Silverstone branding and aggressive styling. If you prefer subtle cases, the PM01 definitely isn’t for you.
Interior Layout & Component Compatibility
Quick Answer: The PM01 offers exceptional component compatibility with support for graphics cards up to 438mm and CPU coolers up to 167mm tall.
Opening the PM01 reveals a thoughtfully designed interior that prioritizes cooling and compatibility. The layout follows a traditional ATX design with modern improvements.
Motherboard support extends from Mini-ITX all the way to E-ATX (up to 272mm wide), though E-ATX boards will limit cable management options. During testing with an ASUS ROG Maximus XII, clearances were adequate but tight.
✅ Pro Tip: Remove the top HDD cage if using graphics cards longer than 322mm – this extends GPU clearance to the full 438mm.
Storage options prove generous with mounting points for up to 8 drives total: 2x 3.5″ + 1x 2.5″ in the main cage, 3x 2.5″ behind the motherboard tray, and 2x 2.5″ on the PSU tunnel cover.
My RTX 3080 (320mm) fit comfortably with room for push-pull radiator configurations. The 167mm CPU cooler height accommodates most tower coolers including the Noctua NH-D15.
Power supply clearance extends to 220mm with the HDD cage installed, or unlimited length with the cage removed. My 180mm Corsair RM850x left plenty of room for cable management.
Build Experience & Installation Process
Quick Answer: Building in the PM01 takes approximately 90-120 minutes for experienced builders, with some cable management challenges due to limited rear clearance.
My first build in the PM01 took 95 minutes from empty case to POST. The process started smoothly with clearly marked standoffs and an included speaker for troubleshooting.
Motherboard installation proved straightforward thanks to the centered standoff that holds the board in place while securing other screws. The I/O shield area provides good clearance for thicker shields.
- Step 1: Install I/O shield and motherboard standoffs (5 minutes)
- Step 2: Mount power supply with fan facing down (5 minutes)
- Step 3: Install motherboard and secure with screws (10 minutes)
- Step 4: Mount storage drives in desired locations (10 minutes)
- Step 5: Install graphics card and support bracket if needed (5 minutes)
- Step 6: Connect all cables and manage routing (45 minutes)
- Step 7: Install additional cooling if required (15 minutes)
Cable management presented the biggest challenge. The 22mm of space behind the motherboard tray feels cramped with modern sleeved cables. I spent 45 minutes wrestling with 24-pin and CPU power cables.
The rubber grommets help but aren’t positioned optimally for all motherboard layouts. My ASUS board’s CPU power connector required creative routing to avoid visible cables.
⏰ Time Saver: Pre-route your 24-pin and CPU power cables before installing the motherboard – this saves 20 minutes of frustration.
Tool-less drive installation works well for 3.5″ drives, though 2.5″ drives still require traditional screws. The removable drive cages simplify installation significantly.
Cooling Performance & Thermal Testing
Quick Answer: The PM01 delivers exceptional cooling performance with CPU temperatures 3-5°C lower than competing cases, but the stock fans produce 45-48 dB of noise at full speed.
This is where the PM01 truly shines – and also where it stumbles. My thermal testing involved a Ryzen 9 5900X with a 240mm AIO and RTX 3080 under sustained load.
With stock fan configuration (3x 140mm intake), CPU temperatures peaked at 72°C during Prime95 stress testing, while the GPU reached 76°C in FurMark. These results beat the Fractal Meshify C by 3°C and NZXT H510 by 7°C.
“The PM01’s thermal performance is genuinely impressive, but you’ll want to budget for replacement fans unless you wear headphones constantly.”
– After 45 days of testing
The included Silverstone fans move serious air – approximately 110 CFM each at full speed. However, they produce an annoying drone at anything above 60% speed, measuring 45-48 dB from 60cm away.
Replacing the stock fans with Noctua NF-A14s reduced noise to 38 dB while maintaining similar thermal performance. This $60 investment transformed the case from borderline unusable to genuinely excellent.
Radiator support impresses with mounting points for up to 360mm in front and top simultaneously. My 280mm top-mounted AIO fit without RAM clearance issues thanks to offset mounting holes.
For AIO cooler compatibility, the PM01 accommodates virtually any configuration. Front-mounted 360mm radiators work best for CPU cooling, while top-mounted units better suit GPU-focused builds.
Cable Management & Storage Solutions
Quick Answer: Cable management in the PM01 is adequate but challenging, with 22mm of rear clearance and limited tie-down points compared to modern standards.
Cable management represents the PM01’s weakest aspect. The 22mm clearance behind the motherboard tray barely accommodates modern cables, especially sleeved varieties.
The case includes seven rubber grommets for cable routing, positioned adequately for most builds. However, the lack of a PSU shroud means careful planning is essential for clean aesthetics.
Velcro straps would improve the experience significantly – the included zip tie points are sparse and poorly positioned. I added my own adhesive tie-down points for better organization.
Storage cable routing proves particularly challenging. SATA power and data cables for drives mounted behind the motherboard tray create bulk that prevents the side panel from closing easily.
- Cable Space: 22mm behind motherboard tray
- Routing Holes: 7 rubber grommet passages
- Tie Points: 12 integrated tie-down points
- PSU Shroud: None in base model
