Since you likely can’t find the original pamphlet, here is the community-sourced checklist for building in the SMA8.
Comprehensive Guide to the CaseLabs Magnum SMA8: Assembly, Specs, and Mastery
The CaseLabs Magnum SMA8 remains a legendary icon in the world of high-end PC building. Known for its unparalleled modularity and all-aluminum construction, it was designed specifically for enthusiasts who prioritize extreme liquid cooling and absolute customization. Because CaseLabs cases traditionally ship "flat-packed" or fully disassembled, having a clear understanding of the CaseLabs SMA8 manual and assembly process is essential for anyone lucky enough to own or acquire one. 1. Core Specifications and Overview
The SMA8 is part of the Magnum series and stands out due to its massive scale and dual-chamber design. Unlike mass-produced steel cases, it is constructed entirely from 2.5mm thick aluminum, making it significantly lighter for its size while remaining exceptionally stable.
Dimensions: 25.75" H x 26.56" D x 11.25" W (654mm x 675mm x 286mm). Weight: Approximately 27 lbs (unassembled).
Motherboard Support: ATX, mATX, and SSI-CEB as standard; E-ATX and SSI-EEB support was available via specific tray options. Radiator Support: Top: Up to 120.4 (480mm) with integrated mounts. Lower Chamber: Supports up to 140.4 (560mm) side mounts.
Drive Capacity: Native support for two 3.5" and four 2.5" drives, expandable to 18+ using the Flex-Bay system. 2. Assembly Instructions: The "Ikea-Style" Build
The original CaseLabs SMA8 manual is typically an 18-page full-color booklet. If you are working from a disassembled unit, follow these sequential steps for a successful build: Phase 1: Frame and Panels caselabs sma8 manual
Preparation: Lay out all aluminum panels and identify them by comparing with the manual's diagrams. Most assembly is done using a standard Phillips screwdriver.
Top and Front: Begin by joining the top panel and the front panel frame using the included countersink screws.
Divider and Mid-Plate: Install the horizontal divider (mid-plate), which separates the main motherboard chamber from the lower cooling chamber.
Bottom and Rear: Slide the bottom panel in from the front and secure it with counter screws. Attach the rear panel using the central and end screws (typically 11 screws total for the rear).
Feet: Attach the four rubber feet or optional casters to the bottom panel. Phase 2: Internal Components
Drive Cages: Use the included nut driver to install the drive cages. Look for markings like 'F' (Front) or 'T' (Top) on the cages to ensure correct orientation.
Switch Assembly: Mount the power and reset buttons to the front panel using the four provided screws. Since you likely can’t find the original pamphlet,
Motherboard Tray: Align the removable tray with the top and bottom plastic rails and slide it into place. Secure it with the four spring-loaded thumb screws.
Clips: Install the frame clips from the clip kit onto the top, front, and side panels to allow for tool-less panel removal. Phase 3: Finishing the Exterior
Hinges and Doors: Attach the hinge kit components to the side panels. Snap the panels onto the frame hinges. If you have the windowed version, ensure you remove the protective paper from the acrylic or glass before final mounting.
Top and Front Covers: Press the top panel down firmly to snap it into place, then mount the front Flex-Bay covers or solid front panel. 3. Advanced Customization and Modularity
One of the reasons the SMA8 is highly sought after is its "Accessory Mounting System." This provides mounting holes along the door perimeters and throughout the frame for custom reservoirs, fan mounts, and lighting kits without the need for drilling.
You do not actually need the CaseLabs SMA8 manual. The chassis is built like a tank using a simple "tab and screw" philosophy. If you look at the case, 90% of the assembly is intuitive.
The only reason to hunt for the manual is to identify replacement part numbers for the Flex-Bay screws (M4 x 8mm Flat Head) or the motherboard tray standoffs. You do not actually need the CaseLabs SMA8 manual
Preservation Note: If you find a PDF of the original SMA8 manual, please upload it to a public archive like [Archive.org]. With CaseLabs gone, you are now the custodian of history. Do not let the manual disappear.

The front I/O (USB 3.0, Audio, Power button) is wired via a Lian-Li style connector block. If your manual is missing, note that the Power Switch uses a standard 2-pin header (PWR_BTN), but the HDD LED uses a non-standard small gauge wire—handle with care.
The official CaseLabs support thread on Overclock.net (spanning 1,000+ pages) contains direct user-uploaded scans of the SMA8 manual. Use the search function in that thread for "SMA8 manual PDF."
Critical Warning: Do not pay for a manual on eBay or Etsy. Scammers repackage free community archives. The manual is free.
The front of the case uses a rail system for mounting drives and cooling hardware.
