I had this old a420n I used to play World of Warcraft, but now I have a better gaming PC that I built that I use now. My brother wants to use it for some light gaming and I was wondering how hard it would be to transfer everything to a case with better ventilation so the CPU wont overheat (which is does now while playing games like Guild Wars)
I put a 7800 GS AGP card in and a 500 watt PSU so the specs are now:
AMD Athlon XP 3000+
1 GB PC 2700 RAM
every thing else is same (the CPU is the same too).
Well it depends. What form factor is the case/mobo of the a420 (ATX, mATX, BTX)? You also need to find out if the mobo uses the standard screw layout.
For the form factor, go to HP's website and see if you can find any documentation about the case.
If everything is standard, it won't be hard at all.
