Ok.. Im going to order some new PC parts..
Im thinking about these.. (yes they are cheap, but I cant go above 3500SEK)
Tower: 
Chieftec DX-01W-D Dragon Super MidiTower 340W ATX (AMD&P4 OK)
Motherboard: EPoX EP-8KTA3L+ KT133A 5PCI 1AGP 3DIMM Audio SocketA ATX
Processor: AMD Athlon XP 1900+ Palomino 1600MHz/1.6GHz 256Kb 266MHz 0.18 bulk SocketA
CPU-Fan: 
GlobalWin SAK68 cpu-cooler SocketA/FCPGA (max 1.73GHz)
Now to me questions. Im not buying a DDR MB cuz then I would need to buy DDR memory (=more money which I dont have). So will my current memory work on the "new" motherboard?
Its one 128MB SDRAM stick + one 256MB SDRAM stick @ 100MHz (PC100).
This should work ok right?
All these components should work with eachother too right? (damn Im a n00b! :eyemouth: )
