I didn't think I could be this stupid, but I clearly can!

I bought an Intel motherboard, model D865PERL as I wanted to use my Pentium 4 Northwood socket 478 cpu and the DDR333 PC2700 RAM.

Foolishly, I didn't check whether the case mounting plate was ATX or micro ATX.

With a bit of hacksawing, I will be able to fit this full-size ATX board into the Dell Dimension case, even though the backplate is designed for micro ATX.

Is there anything else I'll have trouble with?
I'm thinking PSU, mainly.

Any help you can give me is greatly appreciated, please.

You may run into problems with the PSU and the processor heat sink. Everything else should be fine, the PCI/AGP/PCI-e slots should line up in the back. You might also have issue with your I/O ports for mouse, keyboard, usb, etc not lining up.

I wish you much luck.

now why do I think you knew I was going to write this?

Not a chance of putting a full-size ATX board in my Dell micro-ATX case. None whatsoever.
I've spent ages aligning, cutting, measuring. I've bought a 24 pin to 20 pin adaptor for the PSU, my hands are ripped to shreds with sharp metal edges......

I've kept the motherboard. The case is in the bin.

Tomorrow I'm going to buy a nice case. God only knows why I didn't just do that in the first place.

Many thanks for your help.
