A:Answer Thanks for reaching out. This PC should be able to handle a 240MM liquid cooler, however, you may need to attach the radiator to the front as the case may not allow for the radiator to be placed anywhere else. You can refer to the case for more information, Thermaltake G21. If you have any further questions or concerns then please do not hesitate to give our tech support agents a call for any assistance; we're always happy to help.
