Why don't you just take the essentials out like the CPU, graphics card, RAM, hard drive etc and just transplant them into a new case and a new motherboard.
Can't you just do that? I'm sure DELL uses standard CPU and Ram.
The CPU I am sure would work, the RAM is just another question.
Why did you buy a Dell if you wanted to change it around so much?
because when I purchased this for $1100 six months ago, I didn't know nearly as much about computers as I do now. I did, however learn a lesson (never buy from Dell if you're going to upgrade lol). I've purchased a new psu, tv tuner card, and gfx card for this piece of crap...I really wish I would have listened to my friend and built my own.
As for purchasing a new case/mobo...no way, I'm not gonna spend any more money (plus I'd have to buy an OS)
