SATA cable confusion - straight or angled

For my upcoming rig in a couple of months, I can't find any info on which SATA cables are best. I'll have 2HDD's and 2 optical drives, and probably use a Gigabyte X38 motherboard, unless the X48's are out by then. So, I have read that the angled cables are very good, but there are Right and Left angles, angle to angle, straight to angle, straight to straight. Is it best to put the angled end on the HDD's or mobo? Will Left or Right angle mess me up? Then thee's the more important question of which exact cable configuration is best and neatest. Also, for a full tower case like TT Armor, NZXT Zero, or some other, will the 18" be long enough, or should I go for the 24" and hide excess cable in an unused drive by? Thanks all for reading and hopefull posting back. Should this topic be in the New Build section? Seems like this area is busy, and with lots of very knowledgeable people.

^Agree. Selecting the cable depends on your case size,motherboard layout, cable management,etc.

The only meaningul difference between the straight and angled cables is exactly that, one is straight and the other is angled.

Depending on the interior of your case and how crowded it may or may not be and how fussy you may or may not be about neatly arranged cables/case interiors, the choice is up to you.
