In this shot it looks like you had the same kind of offset slot problem I have, in the other not so much?View attachment 27206View attachment 27207
only had to slice the PSU side off for this build, but then random bits of metal and a ton of JB weld to fill in all the gaps. printed a cover for the IO shield area as thats where i put the sff power supply. The case is actually a 15x15x7 junction box that had to be cut with a grinder
Difficult to show the 3.8mm offset required to fit the 9500/PEx boards. But easy enough to see that the rightmost slot edge will be a perfect overlay for the resultant gap.
After the grlf flies home Sunday I can get down to the grinder/cutoff nitty gritty.
Crosshatched sections show the absolute minimum I could do in case mod, but will be doing a bit more to fair the new black slot section in across the back. DB-25 port A will work for the SCSI port if I file the ear out a little, even less as shown for the speaker/microphone ports above ALARMS.
These two shots detail the further cutback I need to do for fitting the mobo. Will work nicely for supporting the Board's Memory/ROM slots.
