This computer being smaller I was worried about PSU and GPU fitments. Although I had to remove the side panel latch, I was able to fit a larger 750w PSU and a MSI Armor RX570 4GB in pretty easily. The $20 SSD made this a zippy, cheap, and capable PC ready to play games with ease.If you plan on upgrading this to a gaming machine just be sure the PSU is a standard size and avoid longer GPUs.
