I doubt I'll ever build my own rig again with prices as low as they are.
All you have to do is buy a Dell with a few slots to slap in a nice video card and sound card if you REALLY want for about $600 and you can usually get a 20 or 22" LCD thrown in the deal too.
The bent pins thing is baaaad. Have you (melted) powered it on yet? I'd almost have sent the proc back immediately without trying to hit it with power if you bent those pins.
Come on, you'd miss the angry cursing, wall punching and 3AM nights that comes with building your own rig.
In my experience I still wouldn't trade it for a boxed system; way better bang for your buck when you can put in what you want.
That's just it. Time is money too. It's WAY cheaper for me to go the Dell route and just slap in the few things they didn't come with (or were way too high to upgrade through the vendor.)
I gotta disagree with the more bang for your buck.
Just for shits... spec out a dual core 2.4Ghz proc, 3GB memory, 320GB HD, DVD-RW, Integrated sound & video on the MB and a 19" widescreen LCD capable of running 1680x1050. Don't forget the cost of a legal copy of XP Pro or Vista Home Premium. Can you keep it under $380 shipped? Mine was 330 plus shipping & tax.
