Upgrading a Dell Dimension L550r (yeah its old)

[pimpoutoldstuff]

I have finally decided that a laptop is no good for gaming and I'm wondering if I could upgrade this really old computer i have or if I should just buy a new one. I'm really short on cash though so I don't know what to do.

I don't need a serious gaming computer, just one that can handle something like World of Warcraft.

What I plan to put in it:
Graphics - SAPPHIRE Radeon 9600 Pro Advantage 100562 Radeon 9600PRO 256MB 128-bit DDR AGP 4X/8X Video Card - OEM

Processor - Intel Celeron D 330 Prescott 533MHz FSB Socket 478 Processor Model BX80546RE2667C - Retail

Memory - pqi POWER Series 512MB (2 x 256MB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered Dual Channel Kit System Memory Model MD4412UOE-X2 - Retail

I just copy/pasted all that from newegg, and I don't know if I'm gonna get ripped off or if anything else works.

NONE of that is gonna work in your laptop, I have a feeling. I know for certain that the RAM won't (it's not laptop RAM), nor will the video card (you can't upgrade the video card on a laptop, sorry).

What I meant was the old computer is a desktop.

I have already searched for laptop upgrades, and yeah, nothing
