Thinking about getting a Laptop

[Homeskillet21]

Let me start by saying, please forgive me if this thread doesn't fit here. I do not come here much, so sorry.

Ok, so lately I've been thinking about getting a laptop. Reasons being I pretty much quit gaming, I want something I can carry around with ease and all I will use it for is entertainment and school now. Anyways, I was wondering if you guys can help me estimate some of my parts. Now I built my computer, but once I built it, I never paid much attention to staying into computer building but still know how. Since I guess I am an amateur, I don't know the value of some of my stuff. (Although I did some recent upgrades so I can give myself rough estimates, but I consider you guys much more accurate than me.) Ok, here is my list:

19" Benq Monitor, 16ms FP391 - Got this about 2 months ago for about 350$
AMD Athlon XP Mobile 2500+ - A recent upgrade my friend suggested. Had it overclocked to 2.4ghz and works great. Also only 2 months old.
Kingston HyperX 184-Pin PC-3200 Ram 1GB - As recent as the new processor.
ATI X800 Pro Video Card - Fairly recent, about 3 months old with added heatsinks.
Motherboard Abit NF7-S - Had it since the beginning. About 2 years.
Thermaltake Copper Heatsink thing - Had it for 2 years, still works fine.
Creative Labs 2.1 Speakers with subwoofer - Had it for 2 years also I think.
Pioneer 16x DVD/CD Burner Dual-layer - Had it for 10 months now.
Western Digital 80 GB harddrive 7,200RPM - Had it for 2 years.

So just asking for help. Thx. Sorry again if this is in the wrong spot. And I'm not selling any of it yet, but I'm open to offers
