Here's my take on this. I have a Tornado 1000, and love it. I just put all the components (PIII/Voodoo5) of my main system in it, and had forgotten how big it is. I was going to buy a tower, because the Voodoo took up my bottom 3.5 slot in my other case. I decided to throw it in here first just to check. I am no longer going to get a full tower. There is tons of room in here (it's really long), and there's like 5 3.5 bays. That is one area I was worried about, as I plan on having at least three drives in here, and I'm gonna us a 5.25 for a hot swappable drive. I bought mine used w/ no PS. So I bought an Antec 300 watter from Onvia for about $40 shipped.
So the way I see it. If I were to buy one of these new. I would get a 250 version, and an Antec 300 watt PS. Sell the 250 for like $20-$25 shipped, and have one of, if not the best PS's for less then their 300 watt would cost ya. BTW the Antec has a large amount of connections. I wasted money at Rad Shack buying splitters for my Step-thermo 5 fan Athlon. I did not need them with this PS. Oh, and all the fans have pass throughs so you only need one PS connection.
Get one of these cases, they rock.
If you're a do it yourselfer (I'm lazy myself). They sell this case as a YYT Ranger or something for around $75. Just ask Red Dawn, or another board member that builds a lot of systems, and they may know the actual model. You could then just add your own fans, as time/money permits, and still do the PS deal like I said. This may keep you closer to the $100 mark if you do it smartly.
Oh one more thing. This sucker is pretty loud. I am thinking of getting some Dynomat, or the generic equevilent of the stuff, for it.
Good luck.
