I've had great experience with Creative Labs Sound Blaster cards. If you are looking for just a good performer, then go for the SB Live! 5.1 else get the top 'o' the line Xtigy or whatever they are calling it.

In terms of Shoutcast, do you plan on uploading to Shoutcast? Your computer is fine for that but you will need high speed uploading, like broadband or only a few people at a time will be able to listen to your broadcast. A T1 or T3 would be best.
A good soundcard with a breakout box or front panel inputs for simple hookup would be nice, for example Audigy 2. If you are doing it live, I would suggest a mixer board that accepts records if you plan on using those. Inputs for a turntable or two, 2 CD players and microphone input. Basically what a DJ would use. You could of course record everything to the hardrive and not do it live. The mixer board would still help to hook up various devices to save you time either way.
Back to the soundcard, a professional type card might be better but depends on what you really want to do. For broadcasting on Shoutcast, you do not have to have super high quality sound.
If you want to save your broadcast you will need more hardrive space depending on how many broadcasts you do, but the space you have for now will be fine.
I assume you have checked out Shoutcast and read the info on being a broadcaster. I have not looked at the specs for a couple of years but I do listen quite often.
I will be recording my sets (it's going to be a 2 hour format) onto my hard drive. I feel that there is plenty of hard drive space because I'm only doing a show once a week and I can back them all up onto cd-r after I'm done with that week's show. I have a broadband connection so there won't be any problems with the uploading part.
I was wondering if anyone has ever heard of any incompatibility issues with having a Maxtor drive as the main hd and a Western Digital as the secondary drive.
I do NOT know enough about the antec case to make a proper recommendation. I have to leave that to others who know your case design.
Are you saying the PSU has two fans in it?
My case is totally diffeent manufacture. I run a large fan in front right below the CDROMs which intake air and blows air over the hard drives. The previous case design had 4 80mm fans in that position. I have two large fans blowing air on the side aimed at the memory, CPU and motherboard. There are two 80 mm fans there too - aimed at the hard drive area but those also insure a cooler case air temp. I also have two 80 mm exaust fans on the back of the case. There is an additional 80mm fan exausting air out the top. These are in addition to the CPU and PSU fans.
You will definately need a fan on the CPU itself. While I had no problem with the stock fan for the P4 1.8a 100, I am NOT happy with the stock fan for the P4 2.4b 533. I use a Volcano 7+ CPU fan running over 4000 rpm and sometimes over 6000 rpu.
Do you need all that cooling? Maybe not. I run my FPU portion of my CPU at 100 per cent 100 per cent of the time - See the link about joining the THG team. On my setup, I run about 32-35 degrees C normally and about 45-48 C when running full bore.
