M1 Revision Log

Version	Updates
V6.1	Chassis Adjusted front SFX mount position Adjusted 2.5" mounting holes Adjusted 2.5" drive SATA connector cutouts Added threaded nuts to fan bracket mounting holes Front I/O New punch tooling for smoother edges Audio combo jack changed to black SFX bracket Added/modified flanges to mitigate possible PSU movement ODD bracket Adjusted 2.5" drive mount screw holes for improved stacking bracket support Added chassis mounted 2.5" drive screw access holes Adjusted aux chassis 2.5" drive screw access holes Parts box Removed 120mm fan filters Fan grille count changed to 2 Adjusted screw counts Power cable Changed to right angle
V6	Front I/O Added USB Type C port (requires motherboard 20 pin Type E header) Changed headphone and mic ports to single combo jack All ports use new molds Redesigned I/O bracket with swappable no-I/O faceplate (ports can be removed for cleaner look/slightly better 2.2+ slot GPU compatibility) Chassis Redesigned ventilation holes on bottom and rear to improve airflow Added longer fan mounting slots on the bottom Bottom vents moved to separate steel floor plate attached to underside of chassis Added bottom magnetic dust filter Threaded inserts on PCI bracket Added M4 screw holes for window mounting to chassis Front-right chassis flange reduced, SFX PSU can now be installed from the right side Reduced rear-left chassis flange to facilitate GPU installation Enlarged chassis front GPU passthrough to facilitate GPU installation and provide more room for oversized GPUs Removed four panel mounting clips from side flanges to reduce incidence of oversized GPU conflicts Changed front 2.5" drive mounting to use screws instead of rubber grommets to save space/reduce complexity Integrated fan bracket mount into chassis flanges Added inside-front mounting for SFX PSU Motherboard tray Changed to removable standoffs ODD bracket Redesigned to single piece, now supports 9.5mm and 12.7mm ODD drives HDD cage Redesigned to two pieces, now supports 2x 3.5" drives or 3x 2.5" drives; now allows mounting to inside front 2.5" mount (3x 2.5" configuration only) Top panel Changed to 2mm thick Side panels Extended ventilated area adjacent to GPU Other New 15mm tall molded rubber feet New adjustable GPU support bracket (adjustable for 2-2.5 slot cards)
V5	Front USB 3.0 ports cleaner look (removed port edges flanges) Motherboard tray is now fastened with screws instead of rivets to facilitate replacement or modding Later batches only: Front USB 3.0 ports color changed from blue to black Removed #6-32 screws for PSU mounting (some users were incorrectly using them in M3-threaded holes, stripping the threads) Re-added for later batches, now in a separate labeled bag
V4	Fan bracket changed to steel and magnetic filter is now included Fan bracket mounts changed to allow 2mm of additional travel (allows 140mm fan w/120mm mounting holes to be used alongside a 120mm fan)
V3	Braces added to bottom corners of chassis for increased rigidity/decreased probability of wobbling 0.3mm decrease in side and front panel height Extra QC for wobbling & panel uniformity SFX bracket raised 2mm and flange trimmed for better SFX-L support *(CAUTION: SFX-L is still a very* tight fit with long GPUs, even with the revised bracket)** Additional motherboard standoffs added for compact mATX boards (226x173mm max w/SFX bracket; see thread and google docs spreadsheet) Slightly increased CPU cutout size
V2	Enlarged CPU cutout upward on motherboard tray Additional cutouts at bottom of motherboard tray Move rear 92mm fan and tubing holes down 2mm Additional 3.5" HDD mounting location at forward bottom of chassis Cable tie holes on chassis bottom reduced from 10 to 5 SSD stacking brackets modified to allow stacked 7mm thick SDDs closer ATX PSU bracket moved back to allow more clearance behind chassis front 3.5" HDD cage fixed to work in upper fan bracket position ODD bracket screw holes reduced for better M2 screw fit No top panel screw More SSD mounting screws Extra side panel clips Dome head M5 screws changed to flat head M5 Shortened internal AC cable, changed to left angle Threaded inserts at side bracket mounting points Sub-millimeter increases to exterior panel dimensions to mitigate panel warping Feet color changed to black for silver cases
