ST62K Zen Internals II
The advantage of having a PSU located externally is a lighter build, not that XPCs aren't inherently portable.
The chunky power supply seems to weigh as much as the chassis itself, and it's almost as large. As mentioned, the lack of a discrete AGP card tones down the overall power requirements. Shuttle feels content with this literally brick-like 180w model that's passively cooled. A custom connector mates with the Zen's back panel and a regular 3-pin PSU connection is fed from the mains. The cabling is of sufficient length to hide the bulky power supply out of sight.

And the benefit of not having the PSU inside is highlighted by the above picture. The SB75G2, on the right, is both taller and longer than the Zen. The size differences, though, aren't huge. We suppose that Shuttle's intended Zen market will appreciate its smaller footprint.

Nothing remarkable in the bundle. There's a tiny S-Video-to-RCA convertor for, presumably, TV-Out duties. Both manuals are typical Shuttle, that is, well written and concise. There's also the obligatory XPC feet, various installation screws, and a sachet of thermal grease. We can also see the tiny hard drive IDE cable and a longer cable that doesn't have any immediate use. There's a curious 3.5" blanking plate, for use if a hard drive is installed in the bay. You can guess what the installation CD does.
