I'm not quite sure which model you're talking about, since I didn't notice you mention a specific model number.
I own a LianLi PC-60Plus, and it doesn't have the mobo upside down. I think LianLi only designed a few models this way aimed at the market who would use this as a server, and since the heat-pipe mobos are aimed more at desktop users/gamers, they probably didn't see themselves as undercutting their own market share.
I bought an A8N SLI-Premium and it has a heat-pipe, as well. I would have been pretty disappointed to send back my PC-60 because the quality of craftsmanship pretty much blew my mind. The quality of aluminum, the sturdy fans, the sliding mobo tray---everything all the way down to the wires and thumbscrews are quality.
