Power Supply: Corsair Builder Series CX430 430W
$41.27 on Amazon
With no dedicated GPU, we scaled back slightly on the power supply. But fear not! This 430W hummingbird is a gem at under $50.
The Corsair Builder Series CX430 should be on every poor gamer's power supply list. It's decently efficient, with an 80 Plus Bronze certification to prove it, and it's made by Channel Well, a decent PSU OEM. Even JonnyGuru digs it (even if the review is three years old).
If you think a standalone graphics card is in your future, you might want to consider an alternative power supply with more than one PCIe connector. A fantastic (but more costly) alternative is the Rosewill Capstone 450W, which has two PCIe connectors, and an 80 Plus Gold rating.
Case: Rosewill LINE-M
$38.14 on Amazon
The Rosewill is exactly the kind of case I want for this build. It was designed with Micro ATX motherboards in mind, and it still offers some nice features while coming in under $40 on Amazon.
Two USB 3.0 ports are located up front (which can plug into the header on our Asus A78M-A), drive installation is tool-free, and there's a sizable cut-out in the motherboard tray (after-market cooler installation made easy). If you decide to upgrade later, the Line-M can still hold a full-size graphics card, despite its small stature. Two 120mm fans handle airflow.
Simply put: You'll be hard-pressed to find a finer case for under $40, both in terms of thermal performance and case features.
