Modding storm to rev 2

I have a swiftech storm rev 1 that I just took out of one of my old setups for cleaning. I was looking at the pictures of the rev 2 internals and there isnt really that much difference between the two models. I was wondering if it would be worth anything to try and mod my rev 1 to the current rev 2.

Not worth doing.

ditto

Just buy the Rev 2 top if you want the decrease in restriction. Cathar mentioned that if the modification done to the Storm's top was not done correctly it would cause a negative impact on performance.
