Overall, I'm a fan of the SB86i's aesthetic, and I know that people buy Shuttle's hardware just on its looks, regardless of what's inside. But if the appearance doesn't float your computing boat, there are precious few reasons to seriously select the SB86i. Just to recap: it's too loud under heavy load, it's too big and offers you no extra capacity for devices compared to a P-series XPC, locks you into their own mainboards whilst using an open mainboard form factor and the range of processors officially supported is less than it could be due to the (massive) cooling solution.
