I'll have to see about the disassembling photos. They are notes regarding it in this thread.
Edit: Here is the best I can come up with on the disassembly:

The "A" in red show the locations of the split-pins holding the front bezel on each side. Use needle-nose pliers to GENTLY pinch them and push them back through the holes.
The "B" in purple sjow the location of the pins holding on the top. There are also two screws in the middle of the case ceiling.
1. It would help if you'd identitified your location, but if its US, try Homedepot.
2. There are cable extensions:

3. I prefer a 3/4" chassis punch and a nibbler to create slots. You can also use a step drill or a deminal.
The step drill probably the cheapest, (assuming you have a drill). The down side is you need clearance behind the hole.

The Dremel is the standard tool, but it's noisey and dusty. Wear goggles or glasses for when you break the cutting wheels. It can't cut round corners.

The chassis punch can be expensive, (but for computer cases you can get by with cheap ones). I find the 3/4 dia. about the smallest I can easily fit the u-channel on.
