ASRock P45XE vs. Asus P5B

You should have no problems, both motherboards are ATX form factor, and the ASRock P45XE should support your Core 2 Duo processor - check to see if it's on this list.

I know this is “solved” but just info for you…The motherboard you’ve picked, the ASRock, is multiple chipsets ahead of the Asus you had. It will be faster and you will be able to do more with it. Also, ASRock’s parent company is ASUS.
From Wikipedia:

ASRock Inc. is a manufacturer of motherboards, netbooks, and HTPCs, based in Taiwan and chaired by Ted Hsu, one of the co-founders of parent company Asus. ASRock was originally spun off from Asus in 2002 in order to compete with companies like ECS and Foxconn for the commodity OEM market. Since then, however, ASRock has also gained momentum in the DIY sector and plans for moving the company upstream began in 2007 following a successful IPO on the Taiwan Stock Exchange.[1]
ASRock has garnered a reputation for good value (cost/performance) with tech websites,[2] including awards and recommendations for some products.[3][4]

One thing you can always look at is the capacitors. If they’re solid caps then the mobo is usually of a better quality. If they look like a cylinder with lid or 2 piece then they’re usually not as high of a quality. That’s just a real quick check you can do on any board you’re looking into buying.
