I had the SSD and PSU already, albeit unused.
It does get an average of 1100 mhash - on deepbit.

Rig at stock clockspeed does 1100-1200 M/hash on deepbit
Um, the screenshot you're showing has the rig outputting less than 1000 MHash/s total. Yes, every so often it will get lucky and temporarily display a speed of 1100-1200 MHash/s on Deepbit. By the same token, every so often it will be unlucky, and will display a speed of 700-900 on Deepbit. You need to take the all-time average, not just the highs.

Well there's your problem. All of these parts are unnecessary for a dedicated mining rig. You definitely didn't need that CPU, or that much memory, or a case, or the SSD, and you could've gone with a smaller PSU to boot (around 800-850W).
A few weeks ago I put together a rig, NEW, for $950, composed of 4x5830s, that outputs 1240 MHash/s (that's average, not peak). So to charge more than that for a used rig that outputs fewer MHash/s, well ... I don't think you're going to find many potential buyers.
Asking $900 OBO - will accept BTC/MtGox USD/Paypal at current exchange rate.
