Ah thats strange, I replied seperately to those posts, I guess I didnt click send!

Fan grill tastes differ between people, I believe the best thing to do is to offer the unit without grills and if the user wish's to use them then they may choose from the many different types available from many retailors. I have made the feet wider to increase the stability of the unit, this of course, becomes less of a worry with 420mm rads etc.

I have offset the rad as this will me to run fans and fan spacers on the side facing us, so once everything is assembled the stand is positioned approximately in the middle of the rad/fan assembly.
