Desperately need a case / PSU recommendation

[slackerinabox]

I have an austin 450 watt power supply that's flaking out on me lately.. System seems unstable and I'm almost positive it's power related.. I just added yet another optical drive to my system and now the drives sometimes don't even get recognized (again, the drives work perfectly in other systems - i really think it's the PSU).. So I need to change my PSU.. My budget is $50 for a PSU or $80 for a case with PSU.. Any suggestions? Here are my specs because I have an unusual amount of drives (using a RAID controller):

Pentium 4-2.4b on a abit bh7 board
Pioneer A04 dvd-rw
Artec 16X dvd rom drive
Seagate 80 gig, 7200 rpm drive
Samsung 80 gig, 7200 rpm drive
WD 40 gig, 7200 rpm drive
1 cpu fan, 1 system fan (system and cpu temps are always normal - I don't over clock)

I don't need anything fancy at all - just something that delivers clean, steady power without sounding too much like a lawn mower. (though i'm not a silent pc zealot)
Thanks for any help guys!

Austin PSUs don't seem to have a good track record. I would highly recommend getting an Antec PLUS1080AMG. It comes with a 430w Antec power supply, which will provide cleaner and more stable power than the Austin ever did.

VANTEC PSU are good too, they look nice and my 650 watt roars with power

Well, this may not be the most popular answer out there, but I have all my junk running on the 350W Antec Smartpower that came with my SLK3800AMB case. I run an OC'd 1900+, two 10K drives, one 15K drive and 3 optical drives with this PSU and all my line voltages are rock-steady. This would fit in your budget and get you a nice case, although it may short you in longevity for long-term power requirements.
