That's my case, I know the PSU goes at the top but I can't but a bottom-mounted one at the top. Can I? As that would block the fan, right?
I looked for the Antec EA-650 but it's £65
mounted either way a power supply sucks air from inside the case and blows it out the back and it can be mounted fan up in a bottom mount case but its recommended to be fan down for safety sake of things falling in some cases even have bottom vents for the power supply fan but in a top mount case the fan will be facing down and sucking warm air from inside the case
