Looks good. I'd go for a Lian Li or Akasa eclipse for the case, those thermaltakes are bit plasticy for me (IMHO)
Replace that PSU with a corsair. Don't know about that CPU cooler, I'd stick with a tuniq tower or a scythe ninja (but I don't know if that one is bad). Samsung sata DVD writer is quite good, and worth considering for the more speed/less cable aspect.
One hell of a system you have there...
