JohnnyLucky :
The micro tower cases can accept an ATX power supply.
What you have to check is the length of an ATX power supply.
If the psu is going to be mounted in the top rear of the case and an optical drive is going to be mounted in the top front of the case, then you have to check measurements of both items to make sure there is enough room for the two items plus cables.
If the psu is going to be mounted in the bottom rear of the case and hard drives are going to be mounted in the bottom front of the case, then you have to check measurements of both items two make sure there is enough room for both items plus cables.
Some of the newer video cards can be quite long. For those you need the check to see if there is enough room from the back of the case to a hard drive cage or anything else that might be in the bottom front of the case. You'll have to go to the manufacturer's web site to find out the dimensions of your particular card.
I stopped in at a Fry's Electronics store this morning to see what's new. I looked at all of the pc cases on display. Those micro Tower cases seemed pretty small. You might want to consider a mid-tower case.

I'm not sure; it's an ACER model and nowhere on the website (or in any of the bloatware) does it specify the type of case. However, it's comparable to many of the shorter towers you might see at Best Buy or other retailers - so it's a somewhat common size. Obviously, it's not a shuttle box or a dell "slimline" form factor but it's shorter than a mid tower. It's dimensions are: 7"W x 17 3/8"D x 13 7/8"H (close approx.). Per JohnnyLucky's suggestion, I measured the distance between the front of the card slot (for the potential graphics card) and realized I have just over 8" of depth room before I get to where the hard drive sits outside of the tray in which it is mounted. I've got four slots and my "C" drive is on the bottom tray. If I can move it to one of the upper floors that would help but I'm not sure as there are designations for "master" and "slave" drives (primary, secondary also?). As for the power supply, I'm fairly confident that I can fit another one in there without disrupting the optical drive operation, as I have a few more inches of room there and the existing stock psu is approximately 6"W x 5 1/2"D x 3"H. If the width and height of most ATX psus are the same than I can handle an inch or two increase in depth.
As I mentioned, I'd like to get the Radeon 4830 but I'm not sure how many amps are required on each 12v rail. Fortunately, AMD has tested and listed psus which should work. Also, since my mobo has only PCIe 1x16 (not 2.0), I'm wondering if it would still be worth it to get such a card - would the performance difference be significant? I always thought any thing would be better than on board graphics.
My alternative, if my upgrade plans are not feasible would be to get a bare bones kit (with a midtower case) and start again - which would cost about an extra $150 vs. ugrading current rig.
Thanks for any suggestions, hints, etc.
