What the BLOK Is Perfect For

• Mid-range builds with a Ryzen 5 or Core i5 and an RTX 3060 or RX 7600
• Office PCs or compact workstations
• Your first self-built PC without overspending on the case
• Professional environments where a discreet aesthetic is a requirement
• Builds with a single-tower air cooler up to 120 W TDP

When You Should Choose a Different Case

• GPU longer than 300 mm (check your specific AIB model)
• Dual-tower air cooler taller than 155 mm
• 360 mm AIO (requires a case with larger radiator support)
• Builds with aggressive overclocking that need more ventilation capacity
• If you want a tempered glass side panel to show off a lit interior

Step 1: Confirm your motherboard's form factor

ATX (30.5 × 24.4 cm), Micro ATX (24.4 × 24.4 cm), or Mini ITX (17 × 17 cm). You'll find this in the board's specs or on the box.

Step 2: Note the exact length of your GPU

Find it in the specs for the specific AIB model you're buying, not the reference card. The same GPU chip can vary by 10 to 40 mm depending on the board partner's cooler design.

Step 3: Decide your CPU cooling solution

Air cooler: check its height. AIO: check the radiator size (120, 240, or 360 mm) and whether the case supports it in the position you need.

Step 4: Now choose the case

With those three data points confirmed, filter for cases that support your form factor, GPU length, and cooling solution. What remains after that filter is your real shortlist. Within that shortlist, choose by design, price, and extras.

Step 5: Check the power supply

All modern mid-tower cases support standard ATX PSUs. But if you choose a Mini ITX or compact case, the PSU may need to be SFX or SFX-L format. Verify this before purchasing. You can browse compatible options in the Hiditec power supply range.

Can I put a Micro ATX board in an ATX case?

Yes, no problem at all. ATX cases like the Hiditec BLOK or the SKY always accept smaller boards because the mounting holes for smaller form factors are included in the motherboard tray. The only result is some empty space at the bottom of the case, which is completely normal and has no meaningful impact on performance or airflow. What never works is the reverse: an ATX board will not fit in a Micro ATX case.

What happens if my CPU cooler is too tall for my case?

The side panel won't close. And there's no elegant fix: you either swap the cooler for a shorter one, or swap the case. Never force the side panel closed when the cooler protrudes — you risk bending the panel, damaging the cooler fans, or destabilising the socket mounting. Prevention is simple: check the CPU cooler clearance spec of the case (found under compatibility or "CPU Cooler Clearance") and compare it to the cooler's dimensions before buying either one. With the BLOK (155 mm limit), the ideal choice is a single-tower cooler up to 155 mm. With the SKY (175 mm clearance), even the largest dual-tower coolers on the market fit with room to spare.

Do I need a modular PSU for good cable management inside the case?

Not strictly required, but it makes a significant difference in the final result. A modular or semi-modular PSU lets you connect only the cables you actually need, eliminating the excess that, with a non-modular unit, you'd have to hide somewhere in the rear chamber. If the case has good cable management features and enough rear chamber depth, even a non-modular PSU can result in a tidy build. But if you want the cleanest possible result, a modular unit is the right call. You can explore the differences in detail in our guide Modular vs. Non-Modular PSUs: Marketing or Real Need?

Is a case with a tempered glass front panel worth it?

From a thermal performance standpoint, a tempered glass front is worse than a metal mesh front because it restricts incoming airflow. The difference can be 3 to 8 °C across components under peak load, depending on the configuration. If aesthetics come first and you won't be pushing components to their thermal limits, a glass front is perfectly valid. If you're running an actively overclocked system, a GPU over 300 W, or a CPU over 150 W, prioritise a mesh front. The BLOK handles this with an ABS front panel with a mesh grille that delivers strong intake airflow without giving up a clean, professional look.

How many fans does my case need?

The minimum effective configuration is one front intake and one rear exhaust. That gives you a basic airflow loop that improves temperatures versus running none at all. The optimal setup for most gaming builds is two or three front intakes and one rear exhaust, creating a slight positive pressure that keeps dust out and moves heat toward the exit. For overclocked builds or high-TDP GPUs, adding top exhaust fans noticeably improves CPU and VRM temperatures. Beyond four 120 mm fans in a standard mid-tower, returns diminish and noise increases without proportional thermal gain.

What's the difference between a gaming case and an office case?

Essentially, design and extras. A gaming case typically includes tempered glass to show off the interior, RGB or ARGB lighting, more fan mounting positions, and greater cooling capacity. An office case like the Hiditec BLOK prioritises a neutral, professional finish, no lighting to distract in work environments, and a robust, understated design. In terms of physical compatibility, both types accept the same components if they share the same form factor. The choice comes down to where the PC will live: a desk in a professional or corporate setting benefits from the discretion of an RGB-free case; a home setup allows more visual expression if that's the goal.
