In-Depth Information
A different Mini-ITX motherboard might have fit the ISK300-65 case with no
problems; the D510MO motherboard might have fit a different Mini-ITX case
without problems. Unfortunately, the only way to know for sure if a particular
combination of motherboard and case will go together smoothly or require
minor case mods is to try it.
In our situation, the problem was a lack of clearance caused by a combination
of the metal port enclosure (labeled H949d in Figure 7-13) on the D510MO
motherboard that contains the keyboard and mouse PS/2 ports, and a project-
ing black plastic expansion connector that joins part of the ISK300-65 case to
the frame, just to the right of the H949d enclosure.
With the I/O shield in place, there was simply no way to slide the motherboard
into position, because we couldn't slide the H949d enclosure past that pro-
truding expansion connector. We considered temporarily removing the as-
sembly secured by the expansion connector and then reinstalling it after the
motherboard was in place, but that looked to be more work than it was worth.
So we decided to use our butt nippers to nibble off excess plastic from the
offending expansion connector, as shown in Figure 7-14. That, of course, re-
quired removing the I/O shield.
Don't Cut Too Much
Remove only excess protruding plastic; leave enough of the connector to keep the
subassembly secured. If you don't have butt nippers, you can use a sharp knife or
single-edge razor blade to remove the excess plastic.

Slide the motherboard into position, carefully aligning the back-panel I/O con-
nectors with the corresponding holes in the I/O shield. Once the motherboard
is in position, examine the rear I/O panel carefully to make sure that none of
the grounding tabs are protruding into jacks.
