The Gigabyte X58 UD3 is, by all reports, a good solid board.
And I go along with hell_storm here. Even with a case window, I do not worry too much about appearance. Quality first, features and layout second, appearance last.
I second the gigabyte X58A-UD3R inexpensive and packs a punch.. it is the board I chose and I very happy with it (using with i7 930 and it got me to 4.3Ghz
