Part 5: Cases and Cooling

The case houses all your components and determines how cool (temperature-wise) and quiet your PC runs.
A good case makes building easier and keeps everything running properly. Let's keep this simple.
Case Sizes
Cases match motherboard sizes:
- Mid-Tower (Most Common):
- Fits: ATX, Micro-ATX, Mini-ITX motherboards
- Good airflow, easy to build in
- Fits on/under most desks
- Best for: Most builds (Our recommendation ↓)
- Full-Tower (Large):
- Fits everything, lots of room
- Heavy, takes up lots of space
- Best for: Extreme builds, water cooling
- Mini-ITX (Small):
- Tiny, portable
- Harder to build, less airflow
- Best for: Experienced builders only
Airflow: Why It Matters
Good airflow keeps components cool and extends their lifespan.
Basic airflow principle:
- Cool air IN from front and bottom
- Hot air OUT from top and rear
- Hot air rises naturally
Mesh vs Solid Front Panel:
- Mesh front: Better airflow (10-15°C cooler!)
- Solid front: Looks sleek but chokes airflow
For gaming PCs: Always choose mesh front
Important Case Features
Look for these features:
- ✓ Mesh front panel (better cooling)
- ✓ Dust filters (keeps components clean)
- ✓ Cable management space behind motherboard
- ✓ Room for your GPU length
- ✓ Enough clearance for CPU cooler height
- ✓ Easy-access front USB ports

Why we love it:
- Outstanding airflow (mesh front)
- Compact mid-tower size

CPU Cooling Covered!
We already recommended the perfect CPU cooler in Part 2:

This handles your CPU cooling needs perfectly. No need for expensive liquid cooling!
Case Fans
The Fractal Torrent Compact includes excellent fans, but if you want to add more:
- Front: 2-3 intake fans (included with Torrent)
