Cheapest Computer setup #HELP

[Arkyo00]

My Computer is extremely old... its about 10yhears old lololololol
well now I want to change it!
I wanna change the motherboard and the cpus etc.
Only the case and the Hard Disk left.
I wonder do i need to change the case?

(I want the cheapest)
P.S. CPU I prefer 2x CPU,@2.5GHz
RAM:4GB

Anyone can suggest a motherboard that could fit these?
If need other information please comment bnelow

You need to replace everything if your hard drive is that old it's probably on it's last leg.

Oh my disk isn't 10years ago luckily,so I want to keep it. My disk is HDD I think...is it called HDD?

Thx though

I'd guess that your case is ATX. Your hard drive is likely pretty close to dead, or useless- I'm presuming it's IDE. Here's a suggestion- maybe not the cheapest ever, but the cheapest I would bother with.
