I prefer the 342 small case, which has good heat dissipation, removable hard disk cage, and it is no problem to install large graphics cards in the future, provided that the small board is used.The big box selects the destroyer K100 or K200. The destroyer imitates the K100, and the workmanship is not as good as the destroyer. The price of JD and Xindan is between 200 and 225, and the cheap 199 on Taobao can be won, which is cost-effective.Of course, if you are sensitive to the price, you can choose the Destroyer.
