Well, with or without money, I think the best way to go about it is to build your own system. So you buy your own case, motherboard, vid card, sound card, CPU and the such and you put it together yourself.
This way, you learn a great deal about how your computer works.
My roomate is intimidated by the idea of building his own system but I think he is missing on a lot of fun and a good learning experience. It really isn't as complicated as people think and you get to build exactly the machine you want, not confined to what Dell or Mac or whoever else thinks you need/want.
Now, if you want to build your own Hachintosh, that is a little more complicated, not everything is compatible with Mac's OS X and you'll have to do some research.
But to build a OS X supported system, I suggest you go with an Intel CPU, an Asus motherboard and a ATI vid card.
P5W MH Deluxe really is the best mobo for a Hackintosh and if you have a lot of money to spend, you'll like that one...

As for cases, you really can't go wrong with
Thermaltake, they really are the best cases on the market IMHO. Unless you are a teenager than you'll prefer the more "cool" plastic cases with all the lights and such crap. Just make sure you get a metal case, don't go near the plastic stuff, plastic cases retain too mmuch heat while the aluminum cases act as kind of a heatsink for the heat generated inside the case.
Me, I wouldn't ever buy a pre-made system, I like building them too much and if you were to give me a system, I would take it apart and rebuid it my way just for kicks.
The project I am working on right now:
Thermaltake Tsunami Dream case (a gorgeous case)
P5W MH Deluxe mobo (lotsa features there)
Intel Core2 Duo Processor E6600 2.4GHz w/ 4MB Cache
Thermaltake Symphony water cooling system for CPU (this one makes NO SOUND whatsoever, even at full blast, I fell in love with it the moment I saw it)
Enermax Liberty 500W Modular Power Supply I sugget at least 480W of PSU, especially if you plan on getting a decent video card.
Now, I just wish Thermaltake would get around to find an add-on or option that would allow me to cool my vid card on their Symphony system .... that would be soooo sweet!

How about a Mac Pro?
I was playing around with configurations, 2 x dual 3 Ghz, 4 gb of ram, 2 x 500 gb hard drives, ATI Radeon X1900 XT (cause the Quadro is pointless, they have the same specs), 2 x 23" Cinema displays (do you need them?), 2 x Superdrives, bluetooth/wifi, wireless keyboard/mighty mouse, the apple extended protection plan (3 years service).
Total: $7,735.00

For that ticket, they better include a naked chick in that box ... and she better be slutty, real slutty!
