Four 7970s, Two PCI slots

[ebildude123]

So I have four Sapphire 7970s (http://www.amazon.com/Sapphire-DL-DVI-I-SL-DVI-D-PCI-Express-11197-03-40G/dp/B009B6Y01Y), a GIGABYTE GA-990FXA-UD3 AM3+ (http://www.amazon.com/GIGABYTE-GA-990FXA-UD3-990FX-SATA-Motherboard/dp/B0055QYKQO), and a Blackhawk Ultra case.

I can fit two 7970s fine but they block the other two ports I need for the rest of the cards. Is there any riser that could fit inside that small space? Maybe a right angle adapter? What if I took off the case of the cards and kept the fans intact?

I highly suggest looking into open air rigs.
