I have very mixed feelings about what Stealth is about to do. My mind started to scream as soon as it comprehended "case modded racks", and not in a positive way I might add.
I very much encourage companies to invest to server rooms. I have seen far too many server rooms that are not adequate for the room's task. Main faults have been poor air conditioning and extreme clutter of wires and cables on floor, on walls and on servers(
!). Not to mention I've even seen one case where it was next to impossible to reach the malfunctioning server(
!). But case modded racks...

The room is supposed to be extremely practical, not extremely cool looking.
Fine, a customer who knows next to nothing about computers visits your server room and sees all that flashyness. Maybe that's a good thing. But what happens when a IT professional visits your company and happens to see your server room if he did not even ask for it? He will likely think the company's ran by idiots.
I'd rather invest in keeping the server room as clean as possible, that gives a good impression to both non-tech savvy visitors as well as pros. Not to mention the fact that to my knowledge not even once has a pro asked to see a company's server room, not-tech savvy visitors probably don't even know to ask about it.
By the way. I should add that when a company also has a server line of products, it has nothing to do with desktops or notebooks. You cannot compare it, you might as well compare totally different companies. That said, I don't know a single company who's desktop and notebook product lines are top notch, but nearly all server lines are. They really cannot afford to make poor servers.
