Mini PCs are nice, but we're getting tons of requests for more ATX coverage. With a profusion of air vents at the top, Xigmatek Vanguard (
available for $70) is a great candidate for convection cooling. Supporting CPU coolers up to 170mm in height, most fanless coolers including dual-towers and NOFAN CR-95C will fit. The front panel, inspired by passive cooling fins, is a nice touch too.
