*cough* Disregarding my aesthetic taste, an ion platform usually does not come fanless because of the additional heat produced by the nvidia chipset. Your best would be to duct it to a 120mm slow speed fan, which can usually fall beneath the ambient noise barrier. Also, the Q110's prebuilt price looks pretty hard to beat, considering a typical ion bundle (e.g. Zotac) already comes at around $150, excluding case, hard drive, and optical disk.
I like how the Q07 looks. It's brushed, black, and has a uniform look to it. I tend to abhor LED lights, windows and grills (P182 owner). Then again, I think Apple has pretty good aesthetic design. These sort of things have to blend into their environment though, it'd probably look out of place if stashed on a cluttered desk.
