5 Reasons Installing RAM in an ITX Case Is More Painful
You may need to remove the CPU cooler or a fan just to reach the slots. In a mid-tower, you open the side panel and push the sticks in. In an ITX case, the cooler often blocks access.
Your fingers must navigate a maze of cables. Compact cases cram everything together, so you’ll be routing your hand around power cables and headers.
The RAM might be behind the GPU, requiring you to pull the whole card out. If the motherboard is mounted that way, a 30-second job becomes a 10-minute one with risk of bumping something loose.
The physical effort is night and day compared to a mid-tower. Mid-tower is one thumb press. ITX is a game of Tetris with your hands.
Plan for extra fiddling if you build in ITX. The rest of us will be done before you’ve removed your second screw.
