Insane Computer in under 5 Minutes Anyone?

Since there's no Zerg Strategy topic I'll make one. I consider this a zerg strategy not only for getting the achievement but for super all-in cheese against another zerg player.

There's an achievement for rushing and destroying an insane in under 5 minutes, and for those of you having trouble it's easily done by zerg, against zerg on a short rush distance map like Steppes of War. It's very simple:

Drone up until 8 supply, then make a spawning pool once you hit the 200 mineral mark.
Save up your moolah until you the spawning pool completes and make 6 zerglings. This will be exactly 10/10 supply as zerg.
-Important- Once you hit 200 minerals, SEND ALL DRONES to the enemy base, and the zerglings once they've finished!
By the time the drones get there the zerglings should be there too, create 2 spine crawlers and as long as you keep your spine crawlers alive and kill the queen it should be GG very soon.

Notes:
- All the timing is pretty perfect as long as you don't slip.
- Try to keep your lings alive since they have more DPS than drones...
- MAKE SURE YOU ACCEPT THEIR GG WHEN THEY ASK FOR IT!
- Have fun?

Another way is to go toss. What u do is u cannon rush. Pick a map with a mineral line that is near to the low ground like Agria Valley. Then, plunk a pylon down at 9 suppl, then a forge, make 1 cannon on the low ground and then plunk 2 on the high ground. Once u do this just drop a few pylons next to their CC and they will GG, Accept the gg or u will be sad

I've only done it the cannon way as well against another toss, will try your strat although Insane drone micro is very good so not sure....
