Build It: A $340 Ultra-Budget Box
Can we build a serviceable rig for just $340? With AMD’s Fusion APU, we’re gonna try
In past months, we’ve shown you how to build rigs for less than $1,000, and we even built a surprisingly speedy $667 PC Value Meal. But what do you do when your budget is half that? Let’s face it, not everyone has half a grand or more to spend on a new computer, and not every build has to be a tricked-out gaming rig. Sometimes you just need a second computer for the family, or an HTPC that doesn’t break the bank. Heck, sometimes you just need a cheap first computer. That doesn’t mean you have to head to big-boxville and pick a prebuilt off the rack. Indeed, we’re betting that with a little elbow grease we can put together a machine for less than $350 that’ll perform basic tasks, if not with a surplus of power, at least without smoking and dying.

How do you build a PC for less than $350? Combine, combine, combine. AMD’s Brazos Fusion APU is great for that; for $110 we got an Asrock E350M1 Mini-ITX motherboard with a 1.6GHz dual-core Hudson M1 APU and integrated Radeon HD 6310 GPU. Bam! That’s motherboard, CPU, GPU, and onboard cooler taken care of. The E350M1 has two slots for DDR3 DIMMs; we’ll use just one 2GB DDR3/1333 DIMM for now.
We chose the Rosewill RS-MI-01 BK chassis for several reasons. First, although it’s small, it’s roomy enough to accommodate one full-size optical drive and two 3.5-inch hard drives. Other Mini-ITX cases are smaller, but require slimline optical drives and 2.5-inch hard drives—too pricy for our budget. The case also comes with a 250W integrated PSU that’s more than enough to power our rig. The case also has one PCI expansion slot, just in case we want to upgrade to a single-slot discrete GPU sometime in the future—the motherboard features one PCIe x16 slot.
For our drives, we picked a DVD burner with solid performance and a low, low price of $20. We also snagged a 320GB hard drive for $40. We know you can get 1TB for less than twice that, but every penny counts.

Step 1: Mount the Motherboard
The first step is to prep the case. The Rosewill case we’re using is pretty simple; to remove the top and side panels, just remove four screws on the rear panel, then lift the panel up and out. Remove the front bezel (but leave it close by) by detaching the clips at the sides and bottom of the bezel.
Before you install the motherboard, insert the RAM into the slot closest to the APU.

Install the motherboard I/O shield, then slide the mobo onto the four raised standoffs at the back of the case, aligning the I/O ports with the holes in the shield. Secure the mobo (above) with four screws (they’ll look like the ones you just removed from the rear panel), then, while you’re at it, connect the 24-pin ATX power cable, as well as the front-panel HD Audio and USB 2.0 connectors. It’s not going to get any less cramped inside the case later.

You should also attach the front-panel power, reset, and LED connectors (above), as the optical drive will soon make access to that part of the motherboard difficult.
Step 2: Install the Optical Drive
Now it’s time to install the optical drive. Slide it into the 5.25-inch drive tray at the front of the case until the mounting holes on the side of the drive line up with the rearmost sets of holes on the sides of the bay (below). Secure with four to eight optical drive screws.

Tuck the remaining length of the ATX power cable underneath the optical drive, and attach the SATA power and data cables. We suggest using the SATA power connector that’s closest to the PSU for the optical drive, leaving the terminating connector for the hard drive. Replace the front bezel.
