Cooler Master has announced the addition of the N400 and N600 to its N Series of computer cases that already features the N200. With these two new cases, the N Series now offers choices in the mini, mid, and full tower size ranges. Both cases have mesh front panels as well as full support for liquid cooling, offering a great deal of cooling possibilities for any system contained within. The differing size of the cases means that there is a choice for all users to make based on their needs when it comes to number of hard drives, GPU length, and internal space.
