Keep in mind that those built in HSP Video chipsets put all of the graphics calculating load on the CPU and it uses up System memory for Video RAM.  Meaning if the video uses 512MB for video Ram, then thats a half GB you don't have for general system memory.  And the 4200 set is considered kind of low end now.  I am not sure how well it is going to work for 3D modeling.  Even my laptop has a 4600 series. And it's kind of slow on Carrara.  I also wouldn't trust a $10 cooler for a Phenom II.   You shoulldn't need any drivers for your hard drives if you are using windows 7.  Or any newer versions of Windows for that matter.  It handles the drives using it's universal drivers.  XP is the same.  I know it's hard to do a system on a tight budget.  But using cheap components, just because of price is never a good idea.  There is a reason they cost less.  The CPU cooler may seem like an incidental component, but it is probably one of the most important components in the system.  If it doesn't keep your CPU as cool as possible, you risk a burnt out CPU when you put it under load.  At the very least, you will drastically reduce the life of the CPU.  You probably could have saved some money on the CPU by getting the regular edition since you're not using a high or mid end cooler, you definitely do NOT want to try overclocking it.  Heck, most people don't even trust the cooler that comes with the CPU to keep those cool.  If you got the full retail kit it will come with the AMD cooler.  And if you will be doing 3D work on this rig, with a built in video chipset, you DEFINITELY need a high end cooler.  Here is what I use, and it works great on my Phenom II X4 955.

Also.  make sure your case is not too crowded.  The Phenom II like all higher end CPUs tends to generate head which needs to have room to dissipate.  You want a case that can move a LOT of air around inside it.  If it is too cramped in there, the heat will build up and result in eventual component failures.  At a minimum use a mid tower like the Antec 900, with one or two 120mm fans in front, one in back and a 120mm or 200mm blowhole fan on the top to suck out the hot air.

The hard and fast rule of building systems is to build it as high end as you possibly can, because it is less expensive and time consuming than upgrading later.  I've been building them for 20 years or so, and I have found out the hard way that that rule is very true.  I hope this info helps.

Quote - I went with the Tiger Direct deal where there was Gigabyte GA-MA785GM-US2H and AMD Phenom II X4 940 Black Edition combo for $199 or so. The board already included an ATI Radeon 4200 as its chipset, and that seems good enough so I don't have any problems with holding off for a bit on getting a separate graphics card.

Even though I still managed to reuse my old case and peripherals, I still had to swap the old PSU for a 650 watt one, get 4GB DDR RAM and upgrade the HDD. (Couldn't reuse the old Maxtor because its stupid SATA drivers didn't want to work.) Oh, and a $10 CPU cooler, the more expensive one I originally ordered and returned wouldn't fit on the motherboard mount...  Still just a bit under $500 for all that, and in the same state as the warehouse - so there were sales taxes. (I could make the drive to their location so the up-side is that the free ground shipping came next day. I'll let UPS deal with the crap-tastic Chicago traffic.)
