Build It Yourself: A Mini-ITX Gaming System For Just Over $500

A Reasonable Price: CPU And Motherboard

Mini-ITX and Intel: When The Price Is Right

We decided to build this rig using an Intel Ivy Bridge-based CPU. Keeping cost in mind, a 3.2 GHz dual-core Pentium G2120 emerged as our only real option.

As long as two cores are enough, the Pentium offers great performance. And while AMD sells quad-core parts for about the same price, they don't fare as well when it comes to cooling and power consumption, both of which are important considerations in such a compact space. This time around, it just had to be the little 55 W Ivy Bridge-based Pentium.

The Right Motherboard: MSI B75IA-E33

MSI’s B75-based B75IA-E33 is a newer board that offers everything we could want from a mini-ITX platform in this price range. Although the form factor limits any motherboard's available features quite a bit, MSI manages to give its B75IA-E33 a logical and usable layout. Even the UEFI menus are arranged nicely. We found this to be a perfect fit for both the build and budget we had in mind.

While there aren't many bundled accessories to speak of, MSI's B75IA-E33 includes all the essentials. The unexpectedly large manual is easy to navigate, though the text labels in the schematics could have been larger.
