The SteamRollerV4 is built in the Lian Li B4-mATX chassis, which is completely tool-less. Every panel comes off by hand, so you will not need a screwdriver to get inside. The only thing to remember is the order: the front panel has to come off before either side panel will slide out.

FRONT PANEL

• Place your hand underneath the front panel
• Slide the panel straight up, lift it away from the frame 
• This one comes off first, the side panels will not release until it does

SIDE PANELS

• With the front panel off, place your hand on the side panel
• With light pressure applied, slide it towards the front of the case
• Pull it straight towards the front out and away

PUTTING IT BACK TOGETHER

• Reverse the order: side panels first, then front
• Line the flanges up and slide towards the front until it stops

That's it, the whole case opens up in under a minute once you know the order.
