Plan B for my 190g

[Ruth]

So does anyone see a downside (besides appearance, which I can somewhat hide and cost) of going with 4 6100 on a controller? I already have 2 of the 6100 and the controller so would just have to purchase the other 2 and 2 more magnets.
I may go and buy a small sheet of 1/2" acrylic today and borrow the hole saw and bit and try drilling that and see how I make out. 10 holes still scares the bejeesus out of me tho.
