I am looking at doing a couple upgrades to my system, and I'm looking for some suggestions.
 
SSD for the OS Drive
I run an OS/Program File drive with about 60 gig of used space. I am looking at adding an SSD drive and would like to keep the budget between $100 and $150. My OS drive does not fill up (it's been 50 - 70 gig for more than 2 years), so I could go as low as a 120GIG. I was initially looking at the Crucial M4 drives, but I am a little worried because of many negative reviews about the drives not lasting. Ultimately I would like the speed of an SSD, but also maintain a little longevity and reliability.
 
Quiet, yet cool running case / power supply.
I have always just run generic cases with generic power supplies. Sick of the noise - LOL! I am looking at getting a quality case and a large enough power supply to handle future MB/CPU and Higher End Video Card upgrades. I don't even know where to begin.
 
Any and all thoughts are welcome - thanks!

Samsung seems to be making decent SSD's, and that's what I used in my current build. The reviews I read online on Samsung were quite positive and I decided on this......of course there are higher end SSD's, but value for dollar, I'm very happy with it. http://hothardware.com/Reviews/Samsung-840-Series-SSD-Review/?page=1. I got the 250GB one and you'd be surprised at how quickly it starts to fill up, but YMMV. 
 
Regarding the PSU, I'd go through some of these reviews and comapre them to see what fits your needs/budget. I personally preferred the fully modular unit just for the super-ease of installation.

If you install very quiet components to begin with, the noise level will be really low.....and of course, the louder ones will result in more noise. So, all the components combined will be the major deciding factor where noise is concerned. 
 
Again, I suggest reading some reviews http://www.anandtech.com/tag/casecoolingpsus  and see what suits your needs. I needed a full tower (Rosewill Thor V2) to house my Noctua D14 cpu cooler (yup, it's humongous), but my DAW is very cool & very quiet. Although this is an older case, I'm really happy with the with 4 fans it came with/ease to install everything (it's a HUGE case with lots of room/airflow). I generally preferred to use slightly "older" parts in my build as they've already proved themselves, but eitherway, it's good to do a lot of research and avoid as much headaches as possible down the line.
 
Good luck!   

Check out the fractal design R4 cases.

Check out Toshiba Q series 256 Gb SSD for $149. Great price. The drive was recognized and formatted on my system, works so far (1st week :) ) Look at the top of offers list in blue section.

I've been running Intel 240 gig SSD's for almost a year without any problems. My case is by Thermaltake and I think the key to being quiet is by using large fans running at slow speeds.

You cannot go wrong with Antec Performance One cases - like the P280.

Fractal Design was mentioned - they look impressive too but I can personally attest - of the (many) that I have built, I have never had a cooler and quieter air-cooled case than Antec P-series.
If you want a quiet power supply, check into Silverstone's quiet series PSU's.

When I was shopping around for my SSD's it seems that Samsung and Intel were always at the top of the list.
At the time of my build the Samsung's were priced more in my range.
 
Just FYI. As Jim from Studio Cat and Scott at ADK have stated often.
SSD's won't make your programs run faster or smoother. Your PC and programs will open quicker (MUCH) but if your streaming your samples and such off a 7200RPM 3GB/per second then that's all the performance you're going to get.
 
To get the best performance you really need to go ALL SSD with a good read time.
A good write time is good too but not as important as a fast read time.
 
Once I get the $$$ I will be getting a 1TB or 2 and be running a full SSD system.
