This is my first real build, though I've added and removed tons of parts on previous pre-built PCs I've owned.
Fry's had a sale on the 3770 ($165 +tax), but my local stores were sold out, so I price matched it to Best Buy. I originally wanted to get an i5-3450 they had on sale for $125, but neither Fry's nor Best Buy had them in stock.
The SSD, HDDs, ODD and OS were transferred over from my previous PC.
Nearly everything else was purchased from Newegg. I tried to get the absolute best deals possible. I think I did pretty well. I splurged on the 27" monitor through a sale from Amazon.
The last item in my build was the video card, which I received last night. Everything else has been running for about 3 weeks with almost no problems, except I feel my CPU temps are too high, and the CPU fan seems to ramp up too much. I removed and reapplied the thermal paste yesterday, and it's helped, but I still think it could be better. I'm thinking of buying a better (and quieter) CPU fan.
I'm transferring over from console to PC gaming. I should be set for a while with this build. I'm also using this as an HTPC, hence all the hard drives. I may build a dedicated HTPC for those, though.
