protip: these are great hacintosh machines, i got one from woot awhile ago and installed an sdd and a compatible wifi card for OSX and am happily running mavericks on it as i type this!
I had one of these at work, but it had 8 GB ram, 2 GB aftermarket video card (for 3D CAD software), and a standard 750 GB HD. It was a beast. It had the best laptop keyboard I’ve ever had. I didn’t want to get rid of it, but the Z-book they replaced it with is pretty good too. 10/10 would buy if needed a web or media computer. Word of warning, though - the stoutness of it makes it pretty heavy.
