Two issues. First, unless you're planning on using some really top end gaming video card, it looks like you're using more power supply than you possibly need. And with power supplies, that's not just a matter of money, it's a matter of efficiency. When your system is running along using less than 25% of capacity, it's not going to operate efficiently at all. A 400w psu would probably be plenty, but even if you want excess, a 500 would be way more than enough, and there are a lot of great choices. You might list your entire system so we'd have a better idea what your actual requirements are. (if you're using some online PSU calculator, they almost always produce grossly inflated numbers). Even if you wanted modular, you could get a SeaSonic M12II 520 or a PC Power and Cooling Silencer MK III 500W (made by Seasonic) for a lot less than you're paying for that Antec. That Antec is also made by Seasonic.
Second, I've never built in that case, but given it's size, I can't imagine that you need a modular power supply. It certainly doesn't look like it from the pictures in the Anandtech review of that case where they used a Silverstone Strider 750W which is HUGE (about 7 inches deep), and, while that psu is modular, it looks to me like they had plenty of room for wires with no airflow issues. Personally, if it was me, I doubt if I'd worry about a modular psu. Some people like them for the looks; for some cases that lack space for extra wires they're worthwhile, but it doesn't look to me like you need it.
