Lian Li is very good. Have no experience with the A70F however, since I use the A77B.
I had not seen that particular case before - seven wide open drive mounts; nice design!
Lian-Li in general make very good cases. 5 external bays will provide you with space for multiple burners, and/or HD caddies, and/or a media card reader. And with 10 internal 3.5" HD spaces, that is great for future expansion. If you plan on having a few SSDs, you can also get the 2 in 1 adapter to pack even more in the case. But it's a bit of problem for cooling (2x 120mm intake fans, 1x 140mm exhaust fan)
I personally like, for the solid look, the PC-Z70. It has a bit less drive space (3x 5.25" external bays, 9x 3.5" internal, but 2x 2.5"). But it is designed for hotswap of drives. Another plus, it's the 2 top fans to cool it down further (3x 120mm intake, 2x140mm + 1x 120mm exhaust). Something the PC-A70F does not have. Food for thought! ;-)
It's good to create a bit of a positive pressure in the case, but not so much as to create a "convection oven" effect. ;-)

Actually, the PC-A70F has 2x 140mm intake fans and 2x 120mm exhaust fans. Thanks for pointing out the PC-Z70 since I had not seen it before. I like the look and it certainly has plenty of fans. Unfortunately it's about twice the price of the PC-A70F and I don't have your "unlimited" budget.
Oups, sorry about that, must have alt-tabbed in the wrong window when I was looking at the specs. hehe Distractions, distractions!
