Editor's Note: At $89.00, this case provides a solid foundation for a custom build that feels significantly more expensive than the components suggest.

Performance & Build Quality

The 316L stainless steel construction feels substantial and resistant to daily wear. Its polished finish and precise dimensions ensure that standard NH35 and 4R36 movements fit snugly without unnecessary movement inside the chassis.
