Depends on your riser type. On some cases such as the SOLO they are around 7.5mm tall, the standard ones around only 5mm tall. You wont break the solder points, but the cable itself. Sleeving for under mobo = horrible. Everything will go okay, provided that you lay the wires flat with none of the strands stacked on top of each other. Its a very time consuming but rewading proccess, just remember to use something like tape to hold the cables down.
In short, mounting under will more likely damage the cable/wire than the motherboard itself.
Generally with short normal risers you can fit:
-Four strand PSU cables (molex, ATX 12v 4 pin), flatten out the wires
-Front IO USB cables (dual sleeved cable or unsleeved)
-ONE SATA cable; do not stack
-Front IO cables (easiest to fit)
-Flat standard IDE cable, ignoring the connectors
-Flex force PSU wires, if laid flat
Use your common sense; is the best advice. I'd use a clear piece of perspex and lay it against the wiring, using the spacers of the motherboard to support it and see how the wires are after they are under the board. Yes, it is okay if the wires are pushing on the board, but too much flex in the board can kill it.
With taller risers... you can do way more (with the inclusion of others) (my case for example)
-PCI-E 6 pin
-more than one SATA cable
-IDE and the header itself
Just watch out for parts of the board like the RAM slots... they can put shitloads of holes in your cables.
