Antec One S3 [10/23] Motherboard installation

2.3 Motherboard Installation

Before proceeding, check the manual for your CPU cooler to find out if there are steps you must do

before installing the motherboard.

Make sure you have the correct I/O panel for your motherboard. If the panel provided with the chassis

isn’t suitable, please contact your motherboard manufacturer for the correct I/O panel.

This case comes with 5 preinstalled motherboard standoffs. These are positioned for Standard ATX

motherboards but can be relocated to accommodate other form factors.

1. Align the motherboard with the standoff holes on the motherboard tray and remember or mark

which holes are lined up.

2. Install standoffs as needed and put the motherboard in.

3. Screw your motherboard into the standoffs with the provided motherboard mounting screws.

Make sure you have the correct I/O panel.
