While they might be pretty and easier to move around, I don't reccoment
using round IDE cables.  With all the wires lumped together, the
interference from one wire can, and does affect every other wire near it
instead of just 2.  This has a negative impact on the bus speed as
compared to ribbons.  I've benchmarked both cables using dbench and I
found the round IDE cable to be WAY slower than the ribbon type.  The
only thing I would use a "round" cable on is the floppy drive. There,
the access speed is slow enough such that you won't notice (or bench)
the difference.
In short (hehe), stay away from round IDE cables.
