Is this upgradable?

[Scarfall]

Hey.

My uncle wants to get rid of his desktop PC, giving it to me. Currently, I play WoW on Low Settings at 15 FPS, on my pre-historical laptop. I know his PC will do more than that, but I want to know if I can upgrade his PC, on an initial 200 Euro budget (for the first, necessary steps). Upgrade at least enough to play WoW at a steady 40+ FPS rate with View Distance and Particle Density in Ultra, and, if possible, Liquid Detail on Fair. I don't care about shadows.

His PC spec is as following:
MS Windows Vista Home Premium 32-bit SP
CPU - Intel Core 2 Duo E4500; 2.20GHz; 46 ºC
Conroe 65nm Technology
RAM - 3.0GB Dual-Channel DDR2 at 333MHz (5-5-5-15)
Motherboard - ASUSTek Computer INC. Leonite2(Socket 775)
Graphics - HP w1907 (1280x768 at 60Hz)
256MB GeForce 8400 GS (ASUStek Computer Inc) 65 ºC
Hard Drives - 244GB Hitachi Hitachi HDT25025VLA380 (SATA) 34 ºC
Optical Drives - HL-DT-ST DVD-RW GSA-H60L
Audio - Realtek High Definition Audio.

It really depends on the PSU. If you have a decent PSU then yeah you can (and the case room).

I don't know my PSU. Should be somewhere here (more info of my uncle's desktop PC). Please help.

you can buy a better core 2 duo and some ram and a better gpu (like an HD 5770) , but it totally doesnt worth it seriously , you better sell this for few hundred and buy a new core i5 2xxx built

[ComputerNerd]

You are very limited on the hardware upgrade options, and to be perfectly honest on that hardware even after upgrades you will not reach any decent framerate with ultra settings.
A new PC will offer you considerably more options and while I agree that was not your original request, I think expecting an easy upgrade route to such a substantial improvement is not going to happen without replacing all the core components, being the motherboard, CPU, RAM and Graphics Card.
A task considerably more expensive than you intended, and at that point are better starting from scratch.

If you want to raid 25-mans at high settings that old computer is going to be weak even with 200€ upgrades.

To be totally honest with it you can, depending on motherboard, sink about 300-400€ and get it playable to around 20-30fps at medium/high settings, but you should rather spend 600€ to buy whole new computer which runs twice as fast without carrying over too many five year old parts that will only drag you down.

What would be the most cost-efficient computer to get, to run WoW with View Distance and Particle Density on Ultra with steady 40+ FPS?
