Compatibility issues:
RAM : MoBo (RAM 667MHz, MoBo 800MHz) (you need to replace the ram specification)
CD/DVD drive ITS A LAPTOP DRIVE!!!!
Component Issues:
1) the processor.. you WANT a big L2 cache..the bigger the better, at LEAST 1mb, a dual 512kb cache, isn't bad, but a dual 1024 cache, LEET... Its only like 30$ more, and about a 30% performance increase on CPU intensive programs
2) VERY pretty mobo, the only drawback is a lack of dual memory controllers... not too big of deal, but for 300$ I'd want dual controllers... the 4slots at 2GB each, is BEAUTIFUL.. it'll last a long time.. not to mention can support the "multi-board" vid-cards
3) the case, looks poor for a front "in" for ventilation, not TOO big of deal, since the side input will blow right over the PCI slots... but again, might want to check the front of the case for a fan slot, or possibly consider watercooling to PULL any heat from the CPU outside the case before dissipation...

the case isn't a drawback though, just a precaution, namely if you overclock..
4) the RAM... DON'T CUT CORNERS ON YOUR RAM!!! I "kinda" cut a corner and got a 2 gig kit of GEIL 667MHz DDR2 ram kit.. and well... now it sits on my coffee table.. (it DIED on over volting)... and for 230$.. GO GET OCZ ram TRUST ME! its faster 800mhz, tighter timings, has a lifetime warranty, and EVEN overvolts better, and is guaranteed with Extreme Overvolting EVP up to 2.2 VOLTS!!!! thats INSANE! beautiful to overclock or go nuts, or go hot with...... linky:

the revision 2 OCZ, is a bit more $$$ (50$)... but its better, I'm running the revision 1 2 GB kit (1 @ 1 GB each) on my tower, I LOVE IT.. the stuff is like a tank... and the revision 2 is better than it, its f'in fantastic!
not to mention your board is CONFIGURED for 800 mhz ram.. with the 667 you have picked, it won't even post the BIOS...
5) HDDS are fun to play with, HDDS can make, or break, your system... you get a LOOOOOONG seek speed HDD, lol, its worthless except for mass data storage.. you want to get TOP speed drives, (not nessicirally RPM) and not huge drives either, and put them in a RAID 0..

RAID systems are fabtacular, two drives, twice the read/write speed, 4 drives, 4x... but you have to use either 2 or 4 on a single "readable" drive... if you put 3 drives in the system, like I have, run the solo one for windows (incase the RAID system fails) and the other 2 as a D: or E: or whatever, and install all your demading programs and games on it.. you'll pee yourself on load speeds... I can load 3DSMax8 in 3 seconds...
your drive specs: (the important ones):
Cache 8MB
Average Seek Time 8.9ms
Average Latency 4.2ms
Data Transfer Rate 300MBps (did some research for this)
(These are good seek speeds for the drive, and fairly nice data transfer speeds, but by itself, at only 7200 RPM, its slow...)
($ : GB ratio) 70$ : 200GB (.35c / GB)
reccomendations.. multiple drives, gets expensive fast though, I paid about 200$ for my three drives... and I'm only at 120GB
6) CD rom is a CD rom, I'd use the old one, and can the new one, unless its a DVDR
EDIT!!!!!!
AAAAAK!! the CDROM you picked is for a LAPTOP!!!!! pick another!!!
7) for a video card, GET THE ONE HERE you listed,

DO NOT EVEN CONSIDER THE OTHER!!!... this one is 10$ more, TWICE the ram, FASTER CLOCK SPEEDS!, and I guarantee you, it'll get about 30% MORE FPS!!!!...... its a BARGAIN....
I'm gonna do some more research on the HDD's.... lots of new things out

I've been lookin at HDDS for about an hour now... I'll find a better RAID setup for you within the same $ range...
so far, I'd say an extra 50$ is WELL spent to make the two changes I've mentioned..
