You just 'fake' a border

Fiddle: http://jsfiddle.net/TurGw/3/

Html:

<form action="" method="post">
    <div class='upload-border'>
        <input type="file" name="upload"/>
    </div>
</form>

Css:

.upload-border{
    border:1px solid black;
    width:315px;
}
input[type=file]::-webkit-file-upload-button {
    width: 0;
    padding: 0;
    margin: 0;
    -webkit-appearance: none;
    border: none;
    border:0px;
}

 x::-webkit-file-upload-button, input[type=file]:after {
    content:'Browse...';
    left: 100%;
    margin-left:3px;
    position: relative;
    -webkit-appearance: button;
    padding: 3px 8px 2px;
    border:0px;
}
