The Frontier Achilles has a the ATX form factor. ATX is the most ubiquitous of case standards, providing the largest array of compatible hardware on the market. Using the ATX standard, the case can house motherboards and power supplies with form factors Array. The dimensions of the case itself (LxWxH) are 470mm x 200mm x 430mm.
The case has nine 5.25" drive bays, which is more than enough to house various drives, particularly optical drives. There are no 3.5" drive bays, though, so the large number of 5.25" drive bays is a necessity. The case does have 2 2.5" drive bays, however, so you can store an SSD or laptop-sized hard disk drive separately.
