I loved the original version but it just wasn't deep enough for what I wanted.I decided to extend the side rails, panels, and the handles in order to fit larger things on the rack.This model adds an extra 50mm of depth to the original side rails.Also includes extended versions of LabRax Handles (No Supports) from Shubham Patel. Also added 1-4U side panel expansions for those wanting to expand the height of their Labrax. The original version uses M6x12mm bolts and M6 nuts.I could only get my hands on M6x10mm bolts and these seemed to work just fine.Also check out my standard 244 x 244mm mATX motherboard mount to fit this if thats your thing.
