Bought this for the parts. Case is in very good condition with minor scratches. The Innards are squeaky clean with no visible dust. The 2TB HDD (a WD), DVD writer and fans all look and function like new. The RAM (16GB) are all identical Samsung 4GB sticks. The PSU is an AcBel unit (again, dust-free/squeaky clean) with an Elite primary capacitor and Rubycons on the secondary side, typical of AcBel. As far as this being a cost-effective parts bin goes, this one is a clear winner.The included keyboard and mouse are "new" but extremely cheap; they work, but I can't imagine anyone wanting to use these long-term. Consider them a token addition.
