Well, first the list of components of my pc at the time I bought it:
Mobo: Asus M4A78
Memory: Shitty 2Gb DDR2-800 kingston
HD: Shitty 500Gb Seagate
DVD: Very old CD-RW drive I had around
PSU: C3 (I think) 300W PSU (surprisingly quiet)
Processor: AMD Phenom II x3 710
Processor cooler: Stock
Video card: Radeon HD 4350
Video card cooler: Stock
Case: A 20R$ (~9 dollars) incredibly horrible case
I bought it 1 year ago, at that time I didnt care about noise, and knew very little about PC hardware

My PC stays inside my wardrobe with the door open (only place where I can put it), so it heated a lot (65 ºC CPU at idle). Surprisingly, it was barely audible when I turned it on, but got louder with the temperature rise.
I decided to upgrade it, so I bought another shitty 2gb memory, a radeon HD 4770, a ST500BAZ PSU from seventeam, and a bunch of the cheaper fans avaliable and installed everything (11 of the noisier fans you can think of). It got VERY loud, barely could hear music with the PC on, so I bought an CM centurion 590 case, a fan controller and a CM Hyper 212 Plus cooler. Installed everything and now it is much better, but still FAR from quiet.
I currently have one 120mm adda fan and one 80mm adda fan on the front, both running at 40% of their max RPM, the fans that came with the case one is on the side and one on the back, both running at full speed, also two 80mm adda fans on the top that I leave turned off. Now the temps are great, 30 ºC mobo, 28 ºC processor, 51 ºC GPU and 27 ºC HD (HD almost at the same temperature than the processor o.o)
Now the biggest problem in my pc is the PSU (noisy little fucker), so I want to buy another one, preferably one that will do fine with a mid-range hardware in 5 years. I dont plan to use water cooling, so i guess a 650W PSU is enought. I have, at most, 140 dollars for the PSU. I also want to buy another fan for the CPU heatsink, a cooler for the video card that will probably fit future video cards and some quiet case fans.
I dont want to change the case right now, but later I want to get an Antec P180. The cpu heatsink is great for me for now (just 2 ºC more than the Scythe Mugen 2 and 4ºC more than Megahalems, only 600g).
So, if you have any suggestions it would be great ^^
