I don't think it has ANY 2.0 PCI-E slots at all. Where did somebody mention getting a PCI-E 2.0 board? I'm not seeing that. #
The motherboards suggested have been Z77 boards, and they ALL have PCI-E 3.0 hardware support (Asus P8Z77-V LK, Asus P8Z77-V, AsRock Z77 Extreme4/6, MSI GD65, Gigabyte Z77 UDH-3, Z77 UD3, G1 Sniper M3).
Even 4x PCI-E 3.0 is enough for a normal graphics card up to a 680 or 7970GHz, that is the same bandwidth as PCI-E 2.0 8x - people were running 590s in 8x 2.0 slots, so I'm sure an HD 7870 or GTX 660 will be absolutely fine.
The Switch 810 looks like a space-ship from Stargate or Star Trek, it isn't to everybody's tastes. The plastic is flimsy and looks cheap, and XL-ATX cases are huge. The R4 is as close to silent as it gets and is built out of steel and aluminium, with a very high quality sound dampening material on the side and top panels, and if you are paranoid about temperatures, get a water cooling system in there, but really you won't notice much of a difference, PERHAPS 5°C, which is practically nothing.
The Switch 810 that you love so much is 150.
