Hello gang
Okay I have bought a pre built pc a while back and I'm gonna upgrade it with a new gpu and power supply I've got a power supply sorted... but the gpu I have no idea if it will fit before I buy it. Currently the gpu is amd r9 255 and I wish to put in a amd r9 390 8 gb gpu but I don't know if it will fit. I shall paste various links to the pc and the gpu if someone can take the time I will much appreciate it you guys.

The GPU you have listed is 27.5cm long according to Amazon, you can measure the inside of the case from the back to the nearest obstruction to see if it will fit
