Wanting a Gaming PC

I've been wanting to get a gaming PC, but my only problem is the pricing of them. I've been keeping an eye on the HP Pavilion H8, but that's up to $900USD. Idealy it be sweet to have an Alienware Aurora, and that alone is $1,499USD. I've also considered just making my own gaming computer from scratch. I'm not technological with the inside of the computer, but if I put my mechanic knowledge into it, I could probably do it. Just need a case, and some comonents. So help me. Is there a cheaper gaming computer that is still reliable that I could purchase or can somebody telling exactly what I need for a custom made computer, and if possible some URL to the component or computer so I can see what it is and all that. Thank you!

The alienware aurora is beautiful indeed, but then again it's an alienware. Build one of your own with the help of the hardware forum guys and you'll be fine.

Yeah, never buy a pre assembled computers. They are way overpriced and 9 out of 10 times build with trash hardware components.

Never. Buy. Prebuilt. PCs. Just buy parts and put it together on your own. You can get a decent gaming PC for much cheaper.ArchonOver

This. A thousand times this.

this, buying it by parts and making it yourself is a lot cheaper than premade pcs and have a lot more options, go to newegg.com they have a lot of where to choose, with a 700$ pc or so you should be able to run all games at max maybe without full aa and as.
