I am in the process of building a pc for the first time. I ordered a case, a Lian Li PC-O11DW 011 DYNAMIC from amazon. What I received is still the same case, however it has been custom built already with a custom block and chiller. It even has a power supply included. I am not very familiar with building pcs so I am not sure what I am looking at, and I already have a cooling system in mind. Should I return it? Should I try to make it work because it seems to be quite expensive? I have no clue what to do, please help.
