Changing case of Dimension 9200 or... how to arrange 4 hard disks.

Two options ...

(1)  You can indeed mount one drive in lieu of the 2nd optical drive, if you don't need the 2nd optical drive.    Just get a 5.25" to 3.5" adapter and mount the disk there.   If you're concerned about the ventilation (or lack thereof) in that area, just use a hard drive cooler [e.g. http://www.buy.com/prod/startech-com-5-25-front-bay-mount-dual-fan-hdd-cooler-40mm-1-x-ball/q/loc/101/202956576.html ]     That, plus the drive you have space for below the floppy, would let you mount your 4 drives.

(2)  Use an external case and an e-SATA connection [NOT a USB connection -- that would slow the transfer rates down too much].       You could mount two drives in this case:  http://www.cooldrives.com/midudrnasaen.html
... and connect them to your internal SATA ports using one of these backplate adapters:

Yes, that's what I'm affraid off, that's why I'm asking here. I don't know if I can just move my motherboard and all the stuff to a new case. Plus, besides being able remove my DVD players or the disk drive, I'm concerned about having the proper heat dissipation.

I wouldn't switch cases ==> it's very hard to find a good BTX cases, as that form factor simply didn't "take off" and there are few aftermarket BTX cases.

I'd either mount the drives internally as I noted in my first comment;   or add your extra drives in an external eSATA case.    By the way, if you think you may eventually want to add even more drives, you may want to buy an external case that holds more than just the 2 extra drives you want now.    They are available in 4-drive, 6-drive, 8-drive (and even more) configurations.    The 2 and 4 drive cases are fairly reasonable in cost;   those that hold more tend to get a bit pricey.

I did not even know that BTX form factor existed :(

And yes, the 410 and Dimension 9200 are almost the same computer.

Somehow I don't feel comfortable with the feeling of having my HD's on a little cage besides my computer.
I rather get rid of the two DVD players and get an one external. Anyway, right now it seems I just need 1 more place to the 4th hardrive, because the 3rd is already below the floppy disk.
Actually, the first thing I thought was to remove the floppy disk and get an external, but the space between the two floppy disks bays are too close and I think the hard disks must have more space for ventilation.

So, just to get this in B/W..... Can't I put my motherboard on a big ATX case?

I will answer my self: No. And what a horrible thing is that BTX form factor.

I have my case opened right now, since a couple of weeks ago and it did seemed extrange to me that box of the CPU disipator and the extra fan, but I didn't see it as part of the case and form factor, I saw it more like some extra cooling.
This is an Intel Core 2 Duo 2.4... and I don't see why it would be a problem to put this in a normal CPU.
The backside of the motherboard is fairly simple, just the Audio outputs and a bunch of USB...
Seems like it would fit the back of an ATX... so, what the problem is ?
The cooling? the bolt's places?

The orientation is completely different. BTX and ATX are completely non-interchangeable.

So... yeah, you're stuck between a rock and a hard place... no perfect solution exists.

Yeah, a new computer under my Christmas Tree =)
