I have a 1030. The beauty of the SX-Antecs is that no mods are required to obtain excellent cooling. Cooling pretty much depends on fan selection, and not on case restriction at all. Consequently, very quiet fans can be used four at a time. I'm using four pcp&c silencers, but I believe that the L1A Panaflos are probably better. From there, you could move up to M1A panaflos,(or a variety of good med-flow fans) or even high-output Sunons, if you can take the noise.
Just using the 2 stock fans blowing out the back gives better cooling than many modified cases, simply because their power is not wasted overcoming a lot of restriction.
Dual Xeons wouldn't make this case flinch, with the right fans.
