Got a question for ya, how difficult was it doing cable management on the Antec 300? I just got one for my new build and at my first look, seems like it could be somewhat annoying.
It's not too bad as long as you have a Power Supply with decently long cables. There is enough space between the motherboard and tray to run a few cables like the front panel headers. Then there is quite a bit of space under the Power Supply, which is enough if you need to run a cable to the back. The rest should just be able to go into the space beside the drive bays. Just get a load of cable ties and a bit of patience and it isn't too hard.
