I ordered an Adventurer 9601g case thinking my motherboard was compatible but it isn't. I need to find one that is compatible with my RAM and everything else in a $60 budget. I know it's low but it's all I can do.
It should fit fine although there is the chance that your micro atx board doesn't fit like a glove for obvious reasons. If anything, I'm assuming that the board can only fit into the case with 4 screws as the worst case scenario although I'll be willing to bet that 6 probably do line up. Make sure to trace the holes in your motherboard with a sheet of paper so you can see what lines up with the case. I see points of connection on the MoBo for your Dell, so I see no reason as to why, at least, 4 don't line up; 4 should be enough as long as you don't seat things around the soft points without a bunch of force.
Once you seat your MoBo, there shouldn't be any issue whatsoever with your RAM and the case. They don't really have anything to do with each other.
