Did this mod back when I first got my x51, figured I could share it with you guys.
I have since seen a few people also do this mod, but with a single antenna.

I installed 2 SMA antenna cables. They go from the wifi card to the back panel. This allows me to hook up external antenna.
I went from picking up maybe 5 networks to being able to pick up 25+ networks.... houses in my neighborhood are pretty spread out too, so If I had to guess, I would say my range is well over 1500 feet now.

I am using a pair of Amped Wireless antenna (thats the brand). They are 1 watt powered antenna with a 12dbi gain.
Amped Wireless SB1000 High Power Signal Booster
Along with a killer 1102 card that I had laying around.

No its not enough, plus, that cable will not work either.

You need a 12 inch cable for this.

I got a 10 inch cable and it barely clears the fan, so there is tension on it right now.

But, you need a sma - u.fl cable for this.

How I did it was...
Remove motherboard, remove gpu, remove dvd.
Then mark the place on the back you want the wires.
If you use the computer in its upright position, make sure you put the connectors next to each other so you can have both antenna side by side.
If you lay the computer on its side, then you can put them like I have them (one on top of the other)

I drilled a small pilot hole, then drilled the larger holes. If you start with the big drill bit right away, then you run a chance of having the drill "walk" and it will mar up the case and look bad.

After you have drilled the holes, there is a metal mesh stuff behind it, poke holes in that and run the wires in.

THen reinstall the motherboard and all parts. plug in antenna and fire it up.

Yes cantennas are fun and all, but they are a directional antenna. Unless you are trying to do point to point wifi they are not needed. A good 12dbi powered antenna (I use a pair of 1 watt powered antenna) will give you a good 15-20 block range. Usually thats more than enough to pick up any wifi signals you wish to use.
