current pricing of older (working) components

[A_noob]

As I'm currently in the process of building yet another PC, I'm looking to either sell my first build or, more than likely, part out the pieces. (CL has been a bomb with no replies for the entire system, but then again, $350 may be high considering the current pricing for NEW).

I have researched all the current prices & have a difficult time believing that some of them can be so damned high, especially since most of the stuff has been replaced with newer, faster models.

If I could get some input as to what y'all think this stuff is worth, I'd appreciate it. I've included the "best price" that I could find on the internet for new, but I do understand that things (especially electronics) depreciate rapidly:
Thermaltake Purepower 600 Watt PSU ($70)
ASUS DVD drive DRW-1814BLT ($35)
Pioneer DVD RW drive DVR-212D ($30)
MSI P35 Platinum Motherboard ($130)
ATI Radeon 2600XT video card ($120) YEAH, RIGHT!!!!
Atech XM-4U Multi card reader ($35)
4GB Kingston DDR3 1600 KVR1066D3N7K2/4G ($65)
Linksys Wireless G PCI adapter ($15)
Western Digital 500GB SATA HDD W/D5000AAKS ($75)
Intel Q6600 Core 2 Quad Processor @ 2.4 GHz ($170)

I would look through ebay and see what they're selling for used since that's what you should expect to get for them. search each part, and then filter the search to sold listings only. Your Q6600 is worth ~$50 (i've been in the market for one, so i've been looking)
