I would likewise suggest that you build your own, not so much for cost (although it does tend to be cheaper), but for satisfaction. Just make sure your RAM voltage <= CPU/Motherboard supported voltage. Using 1.75v RAM in a board that only likes 1.65v RAM makes an unstable system :) Having said that, I've always found Dell desktops to be really good. A bit less extra crap pre-installed than some other manufacturers (I'm looking at you, HP), and you have a 50% chance at good support (I've called in 4 times over the years - 2 were teh sux0r, 2 were great help). So if you gotta buy online, Dell is my recommendation. If you build your own, try and find a local shop (here we have bCom and Memory Express) - they will almost always be cheaper than Future Shop and Best Buy.
