Drilled or built-in overflow?

[kentonhq]

1) What would you have (drilled or built-in overflow) for a 120gal (48x24x24) glass tank?

2) Pros and cons of each type?

3) If it's built-in overflow, how many overflow at what size is adequate for a 120gal glass with the size above?

Please help.

either way you end up with holes and overflows, so i'd go with the prebuilt, its faster and less hassel.

I had a 55gal with 2 - 1"1/2 bulkheads at the top of each corner for my overflow, I'll never have that again to loud. Now I have a 100gal with one 2" built in overflow with a stadpipe very quiet.
