A powerful CPU is required to push high-end graphics cards to peak performance. Intel’s Core i7-2600K fits that bill perfectly.

Here’s where our build will befuddle many up-and-coming enthusiasts. Our processor doesn’t care how small the case is, and will operate at full performance as long as it’s kept at or below 98° Celsius. Lacking a small enough performance-oriented CPU cooler to fit within the tiny confines of our smallest case, we were stuck with Intel’s retail-boxed unit.

Had we a high-end, low-profile cooler, it may not have fit our motherboard. Zotac’s H67-ITX is packed with features, but any CPU cooler wider than 100 mm will block its PCI Express slot. We’ve noticed that this problem is consistent across Asus and ECS products also.

Since we never got a chance to review Zotac’s board, we thought it prudent to include the full set of images above. This board does not support manual memory adjustments, but does include the additional memory voltage controls needed for certain modules. The third BIOS image is more important, as users must manually increase the fan speed limit to 100% in order for the Core i7-2600K to operate normally with its stock cooler. We have no idea why Zotac would artificially lower the maximum CPU fan speed by default, since its “smart controls” prevent that limit from being reached unless it’s actually needed.

G.Skill's DDR3-1600 CAS 8 modules defaulted to DDR3-1333 CAS 9. We were hoping for DDR3-1333 CAS 8 at least, since our motherboard’s BIOS doesn’t support manual configuration.

Thermal testing requires a constant, high-load level that’s hard to reach with most of today’s performance graphics cards. That’s because most of the latest enthusiast-oriented products respond to a constantly high load by dropping their clocks to cope. The only current-generation high-end card we had on hand that doesn’t exhibit this behaviour is Gigabyte’s GV-N560SO-1GI.

Many builders might think we're crazy for using a 450 W power supply in today’s configuration. Yet, SilverStone was certain its SFX form-factor ST45SF would be up to the task. Our non-overclocked CPU contributed to a combined CPU and GPU full load power draw of 420 W, which means the unit was only being tasked with a 374 W output according to its 80 PLUS report.

The ST45SF includes a PS/2 form-factor adapter plate.

Our motherboard didn’t include any right-angle cables, so we dug a pair of SilverStone’s 90° cables out of our collection.

Two of our cases required slim optical drives, so we ordered Samsung’s low-cost SN-S083 DVD writer, along with a store-brand mini-SATA adapter cable.
