Zipang 2 Mobo and Case Compatibility

[sprach]

Good day to you all!

Basically I'm interested in purchasing a Zipang 2 CPU HSF and teaming it up with my Phenom II 965.
My specs at the moment are:
Gigabyte GA-MA790FXT-UD5P motherboard
Phenom II 965 CPU
8GB of RAM Kingston HyperX DDR3 1600
Aplus El Diablo PC case.

I would have gone for the Mugen 2, in my opinion the best bang for the buck on the HSF market, but there's the PC case issue, not allowing me to mount a tower cooler unless I detach the side panel fan. The side panel has a 330/360 side fan for cooling GPU cards and the motherboard, which i find pretty well performing, so I'd rather not uninstall the fan on side panel.
Questions:
1. Is the Zipang 2 compatible with the Aplus El Diablo PC case with the side panel fan installed?
2. Would the Zipang 2 be compatible with the Gigabyte GA-MA790FXT-UD5P
3. Is the Zipang 2 going to interfere with the mobo heatsinks and expansion card mounted on the upper PCIEx slots? I have mounted on the upper PCIEx1 slot of the Gigabyte a X-fi Titanium Fatality sound card.
4. Can i still use all 4 installed ram sticks with the Zipang 2 installed? The ram sticks are short.
In every situation described above the PC case remains the same, namely the Aplus El Diablo.

Thanks,
Sprach

Installed ok and working fine for now. The answer to questions 1-4 is positive, no issues at all, perfect compatibility with PC case, motherboard and RAM.
