That case is a smaller mid size ATX case. Any retail powersupply should be fine cable length wise. When you get into the custom larger cases and full size ATX cases is when you really have to pay attention to cable lengths.
You will be fine. The only cable length issue I've ever had with a case that mounts the PSU at the bottom is the ATX12V/ESP12V cable that plugs into the motherboard next to the CPU. You have to run it directly up and under your dedicated video card. It is definitely long enough, but you can't really tuck it away behind the motherboard for cable management. This is not really an issue, but I've had to do it with every build so far that mounts the PSU on the bottom.
