It may seem tight, but leads to big reduction in friction ? Previous distance was ~0, where a tolerance of +0.125mm meant noticeable friction (like in the prototype, where the riser had to be properly pushed in before inserting it into the Shell). 0.5-1mm clears the riser from the friction-zone, since that distance is larger than the worst-case tolerance scenario.23mm under the mobo is a lot easier to work with, especially if you're not methodical about cable management.
