Portable Gaming PC Build Guide – November 2018

Mainstream gaming performance in a small package.

Portability, price, and performance in gaming desktops usually don’t mix well. Majority of mini-ITX cases support only SFX PSU’s which are expensive and those that can fit a mainstream graphics card are usually expensive. With the recent improvements in PC hardware technology, building a mainstream gaming PC using a small and portable case is now more viable. If you are currently looking for a gaming PC that merges portability, price, and performance, this build guide is for you.

For those who want to tweak the build according to their preferences, see the alternative parts below.

  • All AMD Build: Ryzen 5 2600 | Gigabyte B450I Aorus Pro WiFi | New TOTAL = ₱50,470
  • Cost Reduction: G. Skill Ripjaws V 4GBx2 DDR4 2400 | Corsair VS450 | Western Digital Blue 1TB HDD (WD10SPZX) | New TOTAL = ₱42,930


We have thoroughly tested the AMD Radeon RX 580 8GB and it’s a very capable GPU for playing games at 2560 x 1080 resolution. If you are not interested in performance graphs, you could watch the game play videos below.

For those concerned with temperature issues in small cases, no need to worry. The peak temperature I have observed on the Sapphire Pulse RX 580 8GB is 75 C when running F1 2017 for 30 minutes. That is not bad considering I tested the graphics card in Silverstone SG13 without a front fan and only relying on the PSU’s fan for ejecting hot air outside of the case. Ambient temperature is 28 C.

OS for First-time Builders

Ubuntu MATE is a free and easy-to-use OS (operating system) that can accommodate the needs of a PC gamer. Besides being free and easy-to-use, another great thing about Ubuntu MATE is you are in control of the system updates. You choose when and what to download and there are no forced system updates when restarting the PC.

As of today, there are more than 5,000 games at Steam which are natively available on Linux. That may be meager compared to the total number of games at Steam but Valve’s recent move to enable Windows games to be run within the Steam Linux client boosted by a large amount the number of games that can be enjoyed on Linux. Some of the popular PC games that can now be played on Linux are The Witcher 3, Tekken 7, Dark Souls III, NieR: Automata, and Metal Gear Solid V: Phantom Pain.

    75c is bad and it’s because your poor choice of case and card. There are mini itx cases out there that have better air flow. I have a 1080 strix in my RVZ02 and it doesn’t go further than 60c. AMD RX cards are hella hot and power inefficient, you should’ve gotten an Nvidia card.

    I’d rather replace that SG13 with a Thermaltake Core V1 instead
