As much as everyone hates the waiting game, when you feel that a bargain is sitting right in front of you, you need it, and you can afford it, take it! For instance, the computer I have now has discounts on almost every part, if not all parts.
My Build: http://pcpartpicker.com/p/22gza
I purchased everything except for the GPU, SSD, and AIO. I picked it up for around $580 before mail in rebates. My RAM, HDD, and Case all were on sale or had a Newegg weekend deal. My motherboard had a mail in rebate, and a 4GB RAM stick I sold for twenty bucks. My PSU had another mail in rebate. After all the mail in rebates, my total was around $540. And I don't have a microcenter near me for my i5.
I just purchased my SSD, GPU, and AIO last week. SSD? $75, from a little ad Logan posted in the SSD/HDD sections right in this forum. GPU? All time low of around $210 before a mail in rebate($20 MIR, I think). I picked it up in the morning, and 4 hours later, Newegg ran out of stock. Liquid cooling system was $55, with a ten dollar mail in rebate. Total for just the tower? $870 shipped.
Peripherals. Even here is where I go super cheap mode.
Used monitor from a friend: LG Flatron E2250V 1920x1080 LED monitor. $40. Mouse: E-3lue EMS212. $8. Keyboard: Razer Deathadder 2013, from a lovely TekSyndicate forum member. $70. I have a Creative D200 speaker as a gift from my father(used to work at Creative). I also have my Apple EarPods if needed.
Total for this little rig of mine was under 1K. I'd say not bad, considering Intel. Research the prices when you're about to buy, and snatch up deals as they come and go.
