SATA cable length to get and type

Howdy,

As previously posted, I'll be building an I7-950. The good folks on here have recommend most of the items.

What I'm wondering is what type of SATA cables to get (right angle, straight, combo) and their respective lengths. I'd like the inside of the box to be tidy. The cables are for the HDD and the DVD/CD ROM unit.

I'm not sure whether I should post all the guts of this machine but I'll do so ... I'm hoping more data is a good thing.

If any of the parts don't make sense, please feel free to offer your advice. Or if there's something I'm missing - this is a non-gaming machine. This is a work machine: openSUSE 11.1 + VM's + Oracle. I'm trying to keep this machine quiet. Although I buckled under and picked up the CPU fan which seemed to offer great cooling.

Your help is very much appreciated!
