P35/e6600/ddr2 Basics

I'm trying to figure out my finances for and upgrade, so I figure I need to know what I'll be getting my my old parts.

CPU: E6600 SL9ZL 3726A610
It's been running at 3.5 under water with no problems, and never saw anything over 60* while on air. I've been running it with no problems for 2 years. It may go higher, however I figured 1.4250v in bios is enough for me. Admittedly this is not the best chip for overclocking, but it will still get over a 1Ghz OC.

Mobo: MSI P35 Platinum
No issues with the board, no dead ports. It has 2 Esata ports, 5 Sata, and legacy IDE which could be nice for someone's home server.

RAM: 2x1GB Corsair CM2X1024-6400C4DHX (DHX Heat Spreaders)
2x1GB Corsair CM2x1024-6400C4 (regular heat spreader)

44412 ddr2-800, nothing special, and no great over clocking abilities.

Anyway, any help is appreciated. I'd prefer to sell in a nice bundle, but that will never happen. Also, first appraisal, so tell me if I did something wrong.
