If you want to build the smallest high-powered PC available for $500, this is the guide for you! Based on the compact mini-ITX form factor, it packs in everything you need, and nothing you don't. This ensures that you get a system that can be tucked away anywhere or put on display as a conversation starter!

The October 2019 edition of this guide continues to feature AMD's budget-friendly Ryzen 3 2200G APU, which boasts 4 fast cores plus AMD's potent Vega 8 graphics solution. Thanks to a big price drop, it's an absolute bargain, selling for the same price as dual-cores were going for just a few months ago. It's paired up with a fantastic B450-based mini-ITX motherboard that has a huge range of great features, including built-in 802.11ac networking. Also ensuring that you have a flawless computing experience is 8GB of DDR4 RAM and an ultra-fast 256GB PCIe-based solid-state drive. The system is housed in the excellent In-Win BQ656 case, a version of which we reviewed right here. This system can even fit a slim optical drive and a 2TB hard drive, which we list in the optional components section at the end of this guide.

The $500 Home Office / Theater Mini PC - October 2019


    AMD Ryzen 3 2200G

    There's no better low-cost CPU for a mini system than AMD's Ryzen 3 2200G. Sporting four high-speed cores, along with Vega 8 onboard graphics, it's a complete solution in an ultra-efficient, compact package. It can even allow you to play games at moderate settings, which you simply can't do with Intel's CPUs.

    The Guru's Tip:

    Be forewarned - the cooler that comes with this CPU does not fit in this system, which is why we list an aftermarket cooler later in this guide. Also note that while there is a newer Ryzen 3 3200G, it will not work on any existing ITX motherboards without a firmware update using an older CPU, so don't buy it!


    MSI B450I Gaming Plus AC

    This board is the perfect backbone for a compact system. It offers both HDMI and DisplayPort outputs for the built-in graphics, along with six USB ports, a USB 3.0 header for the system's front USB ports, and plenty of SATA ports. Of course, it also has an M.2 slot, which you'll be using for this system's solid-state drive.

    The Guru's Tip:

    This board even has built-in WiFi!


    Ballistix 2x4GB Sport LT DDR4-2666

    For this build, we recommend an economical but fast 2x4GB kit. The CPU and motherboard easily support DDR4-2666 RAM, and that's what we go with here. Note that we specifically recommend equipping this system with two RAM sticks rather than one, as it results not only in 2-3% faster CPU performance, but also a very significant 20-25% boost in graphics performance.

    The Guru's Tip:

    If you'd like to completely future-proof your system, go for the 2x8GB version of this kit. 16GB is probably more RAM than you'll need now, but with current prices, it's very tempting to buy yourself a bit of future-proofing.

    Solid-State Drive:

    Sabrent 256GB Rocket NVMe

    There's no better way to make a PC feel really fast than to equip it with a fast solid-state drive, and this PCIe-based model from Sabrent blows away the competition, despite under-cutting it in price. It's far faster than any SATA-based model, and world's faster than a hard drive.

    The Guru's Tip:

    Going with a 256GB model provides plenty of storage for typical office and "kitchen PC" duties, while keeping the cost extremely low.


    IN-Win BQ656 Mini-ITX Case with 150W PSU

    You'll wonder why you ever had a giant tower PC on your desk after seeing this little guy in person. It's the perfect home for any family or small office PC. It has space for a mini-ITX motherboard, a single 2.5" drive, and a CPU cooler up to 47mm tall. The best part is that it has a 150W power supply built in!

    The Guru's Tip:

    Note that while this case has support for an optical drive, we're not including one in the basic build, as most people don't need it. With that said, we've listed one in the optional component section of this guide in case you're interested.

    CPU Cooler:

    ARCTIC Alpine AM4 LP

    Cool your Ryzen APU with this ultra-slim heatsink, measuring just 42mm tall. It will fit with just a few millimeters to spare in the case, which has 46mm of clearance, while providing excellent and quiet cooling. Note that this is not an "optional" upgrade - the 55mm-tall cooler that comes with the Ryzen APU is far too big to fit in this system.

    The Guru's Tip:

    This cooler also provides the benefit of nearly silent operation!

    Operating System:

    Microsoft Windows 10 Flash Drive

    Windows 10 was released way back in July 2015, yet Microsoft is adding new features to it all the time, with complete OS updates every spring and fall. It's a truly stable, powerful OS, and one that will go down in history as a true success story, much like the pioneering Windows 95.

    The Guru's Tip:

    This USB 3.0 version of W10 will load in under 5 minutes!

Optional Components

    The Basic Wireless Keyboard/Mouse Combo:

    Logitech Wireless Combo MK270

    Complete your system with this incredibly-economical wireless keyboard and mouse system from Logitech!

    The Guru's Tip:

    This combo uses a single tiny USB receiver, ensuring you'll still have plenty of USB ports left over for other devices.

    Hard Drive:

    WD Blue WD20SPZX 2TB 2.5"

    Want to turn this tiny system into a home server? No problem - just add this high-capacity 2TB hard drive to your build!

    The Guru's Tip:

    This is the largest capacity you'll find in any 2.5"-class drive that fits into standard 12mm-thick drive bays. All 2.5" drives with higher capacities are much thicker and won't fit in this system.

    Optical Drive:

    Lite-On DS-8ACSH DVD Burner

    Want to be able to use optical discs with your system? Then add this DVD burner to your build!

    The Guru's Tip:

    The case and motherboard include all the cables you'll need to install this drive (yes, even the slimline SATA adapter that most mini cases leave out!).


    InWin Chopin with 150W Power Supply

    Get a huge aesthetic upgrade for just $20 with the Chopin, which is the same size as the InWin BQ656 listed earlier, but adds a sleek aluminum exterior for stellar looks.

    The Guru's Tip:

    Note that unlike the InWin 656, the Chopin does not have space for an optical drive due to the solid front panel, but instead offers a second hard drive mount.
