Maximum PC

I'm in need of some appraisals on some hardware...

Here is the list, with specs where needed:

*Gigabyte GA-EP43-UD3L v1.0 motherboard (Full ATX, Socket 775, 4 DDR2 slots, 6 SATA, etc)

* Intel Core 2 Quad Q9550 processor (OEM bulk, used, very good condition, never overclocked, runs perfectly)

*2 GB of DDR2 Memory Non-ECC DDR2-1066 speed (Crucial Ballistix memory with OEM Crucial heatspreaders)

*250 GB Western Digital hard drive (SATA 3.0Gbps, 8MB cache, 7200 RPM -- no bad sectors -- works great -- probably 2 years old maybe)

*750 GB Western Digital Green drive (5400-7200RPM drive [varies], 32MB cache, SATA 3.0Gbps)

If anyone has an idea of what this stuff might be worth, please let me know (either as a combo or individually). I'm trying to decide if I can get more parting out the computer or selling it whole.

One additional thing to consider: if I sell computer as whole (with an ATI RAdeon 4650), with Windows 7 Home Premium 64-bit, about how much could I be looking at possibly getting for a machine with this hardware?

(I'm thinking maybe $400 including everything above and Windows OS maybe...?)
