There's been a rash of small and compact cases and systems lately. Sometimes, though, what you want is a glorious hunk of metal that can take in an enormous motherboard, a cadre of hard drives, and the biggest graphics card you can get your hands on. HBT's Gravity6 case meets those requirements and then some.
The Gravity6 is made mostly of aluminum and has a subdued design, as these things go. The case's main area can take in motherboards in form factors as large as E-ATX, and graphics cards up to 16.5" (42 cm) long. There's room for a total of nine hard drives or SSDs: seven in the case's front section in removable trays, and another two behind the motherboard.
Cooling is one of the Gravity6's fortes. The case's top and front sections can take a choice of a 360-mm radiator, a trio of 120-mm fans, or two 140-mm spinners. Provisions for cooling don't end there. The back of the case has an additional mounting spot for a 140-mm fan or radiator, as does the chassis' bottom, close to the PSU spot. Both the front and bottom fan intakes have magnetically-attached dust filters.
The handy touches don't end there. The Gravity6 has an integrated 8-port PWM fan hub, and 1.26" (32 mm) of space behind the motherboard tray for cable routing purposes. HBT made sure that the PSU shroud is removable for added convenience. Liquid-cooling enthusiasts will be happy to know that there are multiple spots for mounting reservoirs, too.
This kind of hardware-packing prowess usually costs a pretty penny, but that's not the case with this, er, case. The HBT Gravity6 is available right now at Newegg for a reasonable $180.
