This is a hardware recommendation guide I’ve been working on for a while. Thought some here might find it interesting.

Before we start we need to address the elephant in the room. For a gaming system, Windows 7 (or, if you’re a power-user, Server 2008 R2) may be an unfortunate necessity (simply for DirectX/Direct3D 11 and 10 compatibility). It’s a shame, but the latest versions of Wine and CrossOver Games are still targeted at Windows XP and DirectX 9 compatibility (and even for these they are still not 100% perfect, though they are very impressive!).”
