Dell Case/PS compatibility

[qore]

I am seriously thinking of adding a new Motherboard to my dell case.

It is a Demension 8250, 2.4 ghz P4.

I already have a new HD, GFX card, Sound card on it. SO my new board would have to be AGP (GFX) and IDE/ATA (HD) compatible. SImple enough...

Here is my question, What "Good" M-Boards will fit in a Dell Demension 8250 case? Has anyone done so before? Will my Power supply work? Can I use my P4 2.5ghz chip? L:ots of questions basically looking for those who have done it and hopefully learn from them.
I'd like to get as much info, thxs!

Shuaib_01110989 There may be other companies that offer other hardware upgrades to Dell systems, but these upgrades are not validated nor endorsed by Dell.    

The above statement is why I am here.

Has to have been someone around here that has used there basic dell components to make an actually decent computer.

You will find little joy in the exercise. It makes a LOT more sense to just get a nice ATX case (just a few dollars more) and then put all of these components in there. The Dell things are proprietary, and although some have made them work, with some rigging, it is a lot of work that may prove unsatisfactory and unworkable.  I would suggest selling what you have and get the basis for what you want.

I was thinking along those lines already, just wondering what I need in addition.

Considering I had to get a new IDE HD (Seagate barracuda 120g)
New GFX Card (GeForce 6600GT 128mb)
Sound Card (Audigy2)

Whats a good M-board for these to run with and how easy would it be to remove the P4 2.4mhz processor from my current one to a new one?

These are items I need to make sure my new M-board will support aswell as new RAM slots for DDR or something equally better and cheaper than RDRAM crap.

Hard for me to justify a whole new case/M-board etc just to get 1-2g RAM.

Btw have I mentioned I am so glad I found this site, not one n00b flame and I thank you for it.

Opinions vary concerning MB's, depending on experiences. I'm partial to Gigabyte boards, simply because I can usually find what I want and have never had problems with them (he says, with fingers crossed ).

edit: I forgot to mention that Dell PSU's are not compatible with anything except Dell. They saw fit to change the pin arrangement on the MB connector. If you know which pins to change, you can make them work by cutting and splicing the wires. Simply to much headache to contend with.
