can Nema 23's be placed inside box tubing X / Y axis

[Hulksmash]

Hi guys, I searched the forum but couldn't find if it had been answered.

As I am really limited on space and trying to maximise the surface area as best as I can

I am debating the following for a machine 1100 x 800mm approx:

1) 60x60x4mm steel box with motors on outside + as bulk buying steel gantry would be also made of 60x60x4 and 180mm in height

2) 80x80x3mm steel with motors inside + as bulk buying steel gantry would be made also of 80x80x3 and 160mm or possiblely 240mm in height

Any possible pros or cons ?

Any advice is appreciated

Mike
