In the past few years, we have covered plenty of amazing LIAN LI PC cases here. The LIAN LI O11D MINI is also worth a look. It is a dynamic mini tower computer case with an aluminum construction, dual chamber design, and modular pump stand and back-panel.
This O11 Dynamic case is designed with water cooling in mind. The back panel lets you choose how many expansion slots you need. You also get multiple tie points and velcro strap channels for cable management. You can order this case in black and white colors.
