Aspire x3200

I bought an Acer Aspire X3200 tripple about three yearts ago and now wish to upgrade it to something around a 3.5 Ghz or i3 or i5 aquiverlent. Unfortunately I can not seem to find the name of the motherboard, lots of numbers and figures everywhere. Can it be done for aroud £150 so that I will have a little over to upgrade the graphic card ? I have tried using the s/n and snid numbers on the Acer web page but as most users probably fin, unhelpful as it is not recognised. Any help is greatfully received.

that uses one of Acers own motherboards, so nothing marked on the board will help
From memory, thats as small form factor unit using an AMD Athlon or Phenom processor. The only upgrade possible would be to a compatible Phenom X4 with the same socket. However I wouldn't bother - the cooling in those only just copes with the installed CPU, if you upgrade you're heading for a problem with it overheating. There isn't room to add an extra fan, or a third party CPU fan
As to graphics, you may be able to get a low profile card in there, but again I wouldn't bother. Theres an nVidia 8200 IGP in there, you'll be hard pushed to find an inexpensive card that would make a signigicant difference without again raising the spectre of overheating.
To top it all, my experience has been that these motherboards are unreliable - at three years, yours has outlasted most of the ones I've seen

My advice would be to run this machine until it fails, and save your money up for a better replacement in a standard sized case. Not a small form factor machine like this
These small machines are really intended as home entertainment TV/Video/Internet systems, not for gaming

Thanks Jon, I probably will see what is available out there.
