I am wanting to change all the components of a system, namely the HDD upgrading from 19GB to 200GB. I have a docking station (thermaltake BlacX) and I am wanting to know how to change EVERYTHING from one drive to the other and it still possibly boot to the new drive once its in the new system by just installing it. This possible?

First things first. If your computer came with a 20Gb hard drive chances are you can't directly install a 200GB hard drive. From the little bit of system specs you do list you may be able to support the drive. Need more info to know for sure. Your BIOS must support drives larger than 127GB. This is called 48 bit LBA compliance. See the link below for more info on this. http://www.48bitlba.com/index.htm Next, you aren't going to get WinXP to boot and run from an external enclosure. This is by Microsoft design.

ok the board it is going to DOES have support for large drives ASUS M3N-HT Deluxe Mempipe. I am pulling from another different board. I just want it to transfer all the information. that's all. So If I can't create a large primary partition then my best bet would be to take the new drive. Install XP home onto it. then get all the files I need from the other computer (in this case the whole C: drive) and transfer to and fro that way?

You can use the USB drive to clone from the computer to the USB. Get the cloning software from the hard drive manufacturer's site. Either brand but probably better to get it for the 200GB. Not sure if you can clone to a multi-partitioned drive or not with those free utilities. A clean install is always best anyway. Cloning from the IDE to a SATA drive will create boot problems too. You need to install SATA drivers in order for Windows to recognize the drive. As I said, best to do a clean install. You can transfer personal files by whatever means available. External drive, flash drive optical disk, Network, direct crossover cable to both NICs.

Ok then I will just do a clean install of XP home and then transfer everything over to the new drive. I was afraid there might be difficulties in going from IDE to SATA. Thanks

You said you wanted to change all the components of your system. Do you mean the MOBO, keyboard, and everything else? Your post isn't clear. "So won’t you give this man his wings What a shame To have to beg you to see We’re not all the same What a shame" - Shinedown

No just changing the RAM, MOBO, CPU, PSU. Everything else is staying the same or close to it.
