There are extensions available for Firefox and Chrome that allow you to define local css rules for sites of your choice. I installed the 'Stylish' extension on Firefox and defined the below rules, which mostly take out unnecessary boxes (borders and background colors). Thought I would share in case some of you like a cleaner design.

@-moz-document domain("forum.monero.cc") {
  body {
    background: none repeat scroll 0% 0% #FFF;
  }
  a, a:hover, a:focus {
    color: #5B9A6F;
  }
  .main-content {
    padding: 0;
  }
  .category-block .panel-heading {
    background-color: #999;
  }
  .forum-block .forum-icon-active {
    text-align: center;
    height: 100%;
    width: 100%;
    line-height: 100%;
    font-size: 40px;
    color: #999;
  }
  .navbar {
    background: none repeat scroll 0% 0% #FFF;
    border: none !important;
  }
  .navbar-default .navbar-brand, .navbar-default .navbar-brand:hover, .navbar-default .navbar-brand:focus {
    border: none !important;
  }
  .footer {
    visibility: hidden !important;
    background: none repeat scroll 0% 0% transparent !important;
    border-top: 0px none !important !important;
    height: 0px !important;
    min-height: 0px !important;
    line-height: 0px !important;
  }
  .footer .container {
    height: 0px !important;
    min-height: 0px !important;
    line-height: 0px !important;
  }  
 .footer, .footer p, .footer p strong {
    color: #FFFFFF !important;
  }
  .reply-thread, .reply-thread:hover, button.reply-thread {
    background: none repeat scroll 0% 0% #FFFFFF !important;
    color: #505050;
    text-shadow: unset !important;
  }
  .reply-thread:hover {
    background: none repeat scroll 0% 0% #FFFFFF !important;
    color: #505050;
    text-decoration: underline !important;
  }
  button.reply-thread {
    border-bottom: 5px solid #505050 !important;
  }
  .category-block .panel-heading, .admin-panel .panel-heading {
    background: none repeat scroll 0% 0% #5B9A6F;
    color: #FFF !important;
    text-shadow: unset;
    border-radius: 2px;
    border: medium none;
    line-height: 45px;
  }
  .post-meta .post-date {
    color: #FFF;
  }
  .panel, .post-panel {
    margin-bottom: 14px !important;
    background-color: #FFF;
    border: none !important;
    border-radius: 0px;
    box-shadow: unset !important;
  }
  .replies-list, .replies-list p {
    background: none repeat scroll 0% 0% transparent !important;
    border: none !important;
    text-shadow: unset !important;
  }
  .breadcrumb, .user-block {
    background-color: transparent !important;
    border: none !important;
    margin-bottom: 0px  !important;
  }
}
