The Smilodon case from Raidmax makes assembling a system easier than ever before. It has a modular, tool-less design that makes the initial build and future upgrades easy. Both side panels latch into place for easy access. For the ultimate in convenience the right side panel has the motherboard tray completed with backplate attached. This lets you install the mobo and all your cards, then lock it into the case as a single unit. Drive installation couldnt be easier. The external bays all use Clicklock technology, just slide the drive into the bay and lock it into place.
