Single it will need to be beefy to run 5 instances with good fps where as you can lack on performance if buying 5 boxes. Example my box runs 5 clients but has cost me close to $2,200 and if I was going to do hardware boxing I'd grab a couple $500 boxes from dell and a hardware broadcaster (not sure how much these run for).
Not entirely true. You don't need to spend a ton of money to 5-box WoW.. even with WotLK, it's not a demanding game.

Here's a foundation for a perfectly fast 5-boxing machine on a budget.. I've built this system 8 times in the last 6 months for people with only slight changes in case/motherboard/videocard/power supply based on their taste or availability of the product for a good price.. the SSD is one I've used twice now, and it's fantastic for our use:
Q6600 $190
DFI/Asus/Gigabyte P45 mid-range motherboard $125-150
8GB DDR2-800 $110
HD4870-1GB/GTX260 $240-260
1TB Samsung Spinpoint F1 hard drive $95
30GB OCZ Solid SSD $75
Samsung DVD burner $25
Corsair/SeaSonic 520-600W Power Supply $100-140
Case of your choice.. $35-150
Mouse & Keyboard $20
Vista Home Premium 64-bit $100
$1115-1315

Add speakers and a 24" montior.. $300-350. Done.. and we're quite a bit under $2000.
