Hi, I want to upgrade/fix my Alienware X51. I got the PC broken from Dell and their shitty service won't help me out. The hard drive, disc reader and LED lights were broken. They have switched the parts but it still doesn't work. After a year now, I've decided that I'll do it myself. But I need to know what can fit in there. I want to upgrade the processor (Intel Core i7-2600 CPU, 3.40gh), the RAM (8gb) I'm a real noob at this, so please help. I'm from EU btw. Price doesn't matter.
