Theres pics of my rig there.
If you look at the links to users other rigs I also had the first gen as well so you can get an idea how they compare.
The fans are a piece of cake to replace. The rear ones use a lockign pin mounting method so you don't even need a screwdriver while for the front you simply pop off th front panel and theres a toolless mount for it.
I just cut the filter out of the front mount because it was too restrictive for my low cfm fans and the mesh where it takes in air catches most of the dust anyways.
