Despite its fairly standard mid-tower dimensions—8.7 inches wide, 20.4 inches high, and 19.3 inches deep—the LanBoy Air is like no other case on the market. It’s more like a cross between an Ikea end table and a Lego set, if a Lego set needed a screwdriver. Its motherboard tray is not only removable and separate from the back panel, but it can switch places with the PSU bracket, if you decide you want your PSU at the top of the case instead of the bottom. Feel like swapping the location of the two three-speed front fans with the three optical drive trays? Go for it—you can even alternate them if you want. The hard drive mounts are more like hammocks, complete with bungie cords, and can be oriented any way you like, though we’d recommend removing them before you move the machine for any reason. This flexibility enables the use of the longest graphics cards you can find. And the floor of the hard drive well includes mounts for two 2.5-inch drives.

The NZXT Phantom is gorgeous in a Dark Side kind of way—whether you opt for Darth Vader black, Imperial Guard red, or our favorite: Stormtrooper white. Though NZXT considers the Phantom a full-tower chassis, at 8.75 inches wide, 21.25 inches tall, and 24.5 inches deep (and with no EATX support), it’s no taller or wider (and barely deeper) than the other mid-tower chassis that make up the rest of this roundup. The Phantom packs seven toolless hard drive trays in a dual-bay configuration that (hooray!) leaves room for long cards like the Radeon HD 5970. We’re not crazy about front-panel doors like the one that covers the Phantom’s five (toolless) optical drive bays, but the Phantom’s door is at least nicely weighted and has a magnetic latch.
