Solid construction, steel, the front panel is plastic, easy to unclip, you get two plastic structures so the box can stand on it's side, the base has 4 wide rubber feet for horizontal use. Within is a metal removeable carrier frame for a single 3.5" hard drive and a Slim (laptop stylee) CD/DVD.
Nice diddy ITX 120W (ostensibly) PSU, normal IEC 240v ac power socket, no ac power cable supplied, a right-angle moulded IEC plug mains lead could be handy if space is tight. PSU has P4 4-pin 12v connector as well as normal multipin ATX connector, just one SATA power connector. Cables for front lights, front audio and front two USB were all there, but not the front E-SATA.
I fitted the basic, old, 40 Watt TDP chipset Intel Atom N270 D945GCLF ITX board, plenty of room, lined up perfectly, back metal panel supplied with motherboard fitted perfectly. However the SATA sockets on this board are in the corner close to the metal frame carrier for the drives, but still usable.
Space for an additional case fan with 50mm hole centres on the right side. Nicely placed ventilation holes in the top lid and right side. I'd say the air flow around the hard drive is good, likewise for the motherboard, at least the D945GCLF, more ambitious CPUs on ITX boards would need a compact height heatsink. The PSU fan which blows out the back, doesn't have a supply of air to suck in, at least from the left of the case, but it's a tiny fan.
A related issue, if you aim to 're-use' an old IDE Slim CD or DVD, and it is equipped with the tiny 'JAE IDE' connector, fitting an adapter card to SATA or IDE is tight, but possible.
Overall, very good bang-for-buck, stylish, looks the part.
