cannibalizing my old computer for parts

I recently got a new Dell (Dimension 5100), and I'm thinking about removing the hard drive from my old one (Dell Dimension L1000R, purchased in 2001) and putting it into my new computer as a second hard drive (slave). Computer stores are 3-1/2 hours away, and I know nothing about hardware, so I need to make sure I have a pretty specific shopping list before I go to the big city!
Can someone tell me exactly what connections/cables/plugs I would need to accomplish this feat?
Also, are there any other parts from my old computer that might be useful in my new one - such as the RAM, perhaps? I have 1GB of RAM on my new computer; I think my old computer only has 128MB, but maybe more is better, even if it's only a small increase?
I have a friend who is looking to add a floppy drive to her new computer (which is not a Dell). Would I be able to take my old floppy drive out and install it in her computer (and use my Dell drivers CD, if needed for the driver)?
How about the internal modem, would that be worth saving for a rainy day?

Some general info relating to the old and new computers:

Old computer's hard drive:
Seagate ST340823A 40.02 GB IDE
Controllers (not sure if these are relevant, but here's the info anyway):
Intel 82801AA Bus Master IDE Controller
Primary IDE controller (dual fifo)
Secondary IDE controller (dual fifo)

New computer's hard drive:
Maxtor 6Y080M0 80.00 GB
Controllers:
Intel 82801GB Serial ATA Storage Controllers - 27C0
Intel 82801BG Ultra ATA Storage Controllers - 27DF
Primary IDE Channel 'Controller](2x)

 

At support.microsoft.com, I found the following:
"Up to four drives "“ hard or CD/DVD "“ can be connected internally to your PC ". If this is a universal truth, then a second hard drive wouldn't even be an option for me, as I already have one hard drive, one floppy drive, and two optical drives.
So should I just can the whole idea? I know there's a way of putting it in a case of its own and hooking it up externally, but I've already got an Iomega external hard drive, so that seems a little redundant.

 

Hi from the other side of the "Rocks ". A couple of my thoughts on using the parts from your old computer in the new one:

The extra 128MB of ram would be insignificant if you already have 1GB. May not be the same type of ram either.

You should be able to add the extra HD. There should be a primary and secondary Hd controller and each will take up to two drives either HD's or CD/DVD's. I am not sure about the compatability of the SATA controllers in the new machine with your old HD. The floppy drive has separate controller and cable, so actually your computer will take 5 drives, one being the floppy. Yes you could attach it externally.

I would read the warranty before opening the box, as some manufacturer's void it if you open the CPU before the warranty period is up.

The old floppy drive should go right into your friends computer without a problem. You will need a floppy drive flat cable from the mother board to the floppy drive and a power connecter. Chances are they are already in your friends computer but check first. The flat cable has different connectors for the floppy than for the hard drive/cd's so shouldn't be too hard to figure out. If the cable is not there, they can be purchased at any Staples/Futureshop stores. Fairly cheap. There are usually spare power connecters inside as well, usually white plugs with four wires running from the power supply. You shouldn't need drivers for it, but may have to activate it in the BIOS.

Well that's my 2 cents worth, I am sure others will fill you in on the missing gaps.

 

Thank you, John!
I've been doing some belated homework on the subject of adding a second drive to a computer, which has enlightened me some about the master/slave business and the cables/connections required, but I hadn't been able to find an answer to my controller question, which you answered nicely for me. Also, your instructions on moving the floppy drive were great - I'll give everything a shot as soon as I have a big enough chunk of time.
Just as happy to know that the additional RAM would be moot. Sometimes I get carried away trying too many new things at once - this way I'll just concentrate on the hard and floppy drives!

 

The SATA HD will have its own controller in the new system and does not
use the primary/secondary controllers at all. SATA has its own connections
on the motherboard so there is no conflict with having an IDE HD inserted.
You need to get a picture of your motherboard that has pointers to where all
the connections are located. It will show where the primary/secondary/SATA
connections are on the MB.

When (if) you remove the floppy from the old system, also remove the cable
and take it with you. Will save a couple bucks.

About the IDE HD controllers (not my best subject), but it wont hurt to try
just plugging in the old IDE drive and giving it a try. I'm pretty sure it will be
OK. Windows should pickup on the fact that new hardware has been installed
and do a search for the needed controller.

Let us know how it works out. Plenty more help from the folks that belong
to this forum.
