Smaller than Flex ATX, yet larger than Mini-ITX, custom mounting holes prevent Shuttle’s motherboards from interchanging with more common standards.
Intel’s X58 chipset provides motherboard model S5165 with two full-bandwidth PCI Express (PCIe) 2.0 x16 slots. However, space constraints forced Shuttle to place these directly next to each other, so builders must choose between dual mainstream (single-slot) or single high-end (dual-slot) graphics devices.
All six ICH10R-integrated SATA 3.0 Gb/s ports are also retained through three internal ports, two rear-panel ports, and one front-panel port. Shuttle's BIOS supports setting AHCI devices as removable, enabling the “Safely Remove Hardware” icon in Windows to empty drive cache prior to removal.

Several standard plugs are included, despite the S5165 motherboard’s proprietary design, so it’s possible to test most motherboard features outside of any case. JP1, for example, is a standard FP audio header, which exists in spite of a different multi-function front-panel header at the other end of the board.
The Realtek ALC888 HD Audio codec provides eight-channel output. A CLR_CMOS button behind it is accessible through a pinhole in the back of the case.
Two Realtek RTL8111C controllers use PCIe x1 interfaces to offer bi-directional Gigabit Ethernet.
A JMB368 controller adds Ultra ATA, but this standard is so outdated that we always disable it. Below it, pin block JP5 is a standard front-panel button/LED connector made redundant by the SX58H7’s custom multi-function interface block.
It actually went to 425W peak with both Prime95 (8-threads) and Crysis GPU bench (2560 Very-High 8x) running at the same time, but that's not a very realistic test.
It shows how the system compares to a standard motherboard and cooler in performance and overclocking. If you want more than standard cooling, you can read any of the X58 motherboard shootouts where a big liquid cooler is used.
Something I found with my current Shuttle box (i.e. SN21G5) is that, having added a modest dedicated graphics card (i.e. NVIDIA 9500 GT), the heat generated by the GPU was enough to keep the main fan spinning at low speeds even when idle. So as soon as the system is put under some load, even if the GPU is idle and only one CPU core is used 100%, the fan will spin at almost full speed generating quite some noise.
Since these small computers are often placed on the desktop, next to the user, the noise level is even more apparent than with other systems which generate similar decibel figures, but rest on the floor, etc. So... should I move away from SFF for my next PC if I want a silent Core i7 system with a GTX 260 GPU?
I can't really seem to figure this part out, at ava direct they have this XPC SX58H7 for about $688 I think, but again nothign conclusive as to what it comes w/....
Case, mobo, PSU. Yes, it's expensive.
