PC on 4 items

I'm pretty horrible at even getting an estimate price on items, so hopefully someone can help me out alittle. I figure number 3 is probably not worth much with it's weird mod, but I placed it in there anyhow. Number one and two is what i'm really interested in.

Any help is much appriciated. Thanks

1. I'd salvage... maybe 10k as is
2. 5-10k
3. 60k+
4. 3-5k+
