Well the dust filters arrived so I spent the whole of yesterday evening blowing the entire case out. Used pretty much a whole can of compressed air while holding the vaccum cleaner hose close to try and drag as much of the dust out as I could. Pretty amazing how much had built up in only a month or two.
I've also replaced the ram cooler with a Zalman offering, it's one of the dual fan units like the new corsair ones, but is titanium in colour to matches the heatsinks on the Rampage board perfectly. Really happy with the result now, the original ram cooler just didn't seem to fit the look and stood out too much for my liking.
So, if I get time this weekend I'll get some pics taken, and a quick guide on the Lian Li dvd bezel covers also.
