How to choose a gaming PC case
A case does more than hold your parts. It decides which graphics card and cooler you can fit, how much air reaches them and how easy the build is. These are the things worth checking before you buy.
Start with the motherboard size
Every case is rated for certain motherboard sizes. ATX boards (305 × 244 mm) are the most common, Micro-ATX (244 × 244 mm) is shorter and mini-ITX (170 × 170 mm) is the smallest. A case that takes ATX also takes the two smaller sizes, so an ATX-rated case gives you the most freedom later. Some larger cases also take EATX boards.
Check the graphics card length
Modern graphics cards are long. Many mid-range cards measure 240 to 300 mm and flagship cards can go past 330 mm. Compare the card's length on its spec sheet with the case's maximum GPU length, and leave a few millimetres spare for cables or a front radiator.
Among SONIC cases, the F301 has the most room, taking graphics cards up to 425 mm.
Think about airflow before looks
A tempered-glass panel shows off your build, but the glass only works well if the case still brings air in. Look for mesh or vented panels, mounting points for 120 mm fans at the front, bottom and rear, and dust filters on the intake. In Pakistan's hot summers, good airflow is what keeps the CPU and GPU from slowing down to stay cool.
Match the cooling support to your CPU
For an air cooler, check the maximum CPU cooler height. For a liquid cooler, check which radiator sizes the case accepts: 120, 240, 280 or 360 mm. A bigger radiator moves more heat, so a 360 mm radiator suits a high-end processor. Every SONIC case takes a radiator up to 360 mm.
Leave room for the power supply and the cables
ATX power supplies are usually 140 to 180 mm long, so check the length the case allows. A power supply shroud and cable routing space behind the motherboard tray keep the build tidy and help air move.
Do not forget front ports and expansion slots
Most gaming cases have USB 3.0 ports and HD audio on the front panel. Count the expansion slots as well: a thick graphics card can take three slots, so seven slots leave room for extra cards or capture devices.
Set a budget in rupees
A case lasts through several upgrades, so it is worth paying for good airflow and room to grow. SONIC cases run from PKR 11,500 to PKR 29,500, and the table below shows what each one offers.

Frequently asked questions
What size gaming case do I need?
If you are unsure, choose a case rated for ATX motherboards. It also fits Micro-ATX and mini-ITX boards and usually leaves room for a long graphics card and a large radiator.
Is a bigger case always better for cooling?
No. A bigger case has more room for fans and radiators, but airflow depends on the fans, the vents and the dust filters, not on size alone.
How much should I spend on a PC case?
A case is a long-lived part, so spend enough for good airflow and room for upgrades. SONIC gaming cases start at PKR 11,500 and go up to PKR 29,500.
