What do you guys think and will it be compatible, Thanks in advance
also is there anything I may be missing? (apart from a graphics card as I hear that the CPU/GPU is fine for what I want [apparently])
More about :350 dollar gaming media rig thoughts parts compatibility
a 2.5 inch hard drive is used for laptops ... mostly ...and will be slower than a 3.5 inch desk top drive . A desktop case will usually have mounts for 3.5 inch hard drives but might have an adapter for a smaller 2.5 inch drive .
You should find a better power supply . Only use 80+ rated units with a feature called Active PFC . That cm is neither . Basically its junk . The Corsair CX 430 is acceptable quality
The msy site is awful to use . I cant search ....
but you should be using RAM rated for 1.5 volts or less
