I bought a Lian-Li PC-C60A from Newegg when it was like $90 or something. When I got it, one or two of the motherboard standoffs were corroded so I sent it back and they had no more to replace it. Price went back up after more came in. Now it's impossible to find the silver version and the price everywhere is $180-220. I regret sending it back now. The standoffs were not user replaceable so that's why I initially sent it back. They were riveted or stamped in place somehow. Not the usual screw in types.
I like that case because it's built around 140mm fans I think it holds 3 or 4 of them. I like big fans and I can not lie.
I've never dealt with any horizontal case with a good layout, this one wasn't the best either. The hard drives were mounted in separate racks that was stack on top of each other and attach to a rail that ran across the length of the case. If you wanted to replace one that happened to be at the bottom you would have to take them all out first to get to it.
I don't think it's possible to design a good case with horizontal position. No matter what you do it's going to suck to work in it.
I'm probably going to buy that case again, but now I have to pay the $200 instead, and it seems like only the black one is available.
Newegg doesn't sell it anymore either, so you have to find it elsewhere, but they still have the link and pics/info up.
Actually never mind all that, I think it's just shy of 11" of space for the card. So 780 won't even fit in that case.
