I don't think its cramped. The IDE and floppy ports point sideways, which some people don't like. (I do because it makes it a little cleaner when hiding the ribbon cables.) My only beef with the layout is the microscopic print on the front panel switch and LED pins. They're impossible to read and I can never seem to find the manual when I need it for this. And if you want to use the SATA ports with an IDE drive, you'll have to use the Abit Seriell2 adapter. The board won't recognize anything else.
It overclocks like a mother. I've had my 2.6C stable at 267FSB (3.471GHz) on 1.575 vcore. (I run it daily at 250/3.25 on default 1.525 vcore, temps @43c on a Swiftech MCX4000B.)
