The model I purchased has a 250W power supply, but the 300W power supply is now more common it seems and likely worth it. One major bonus in my opinion is the fact that the power supply has a separate swicth. Many current ATX power supplies do not have swicthes, a feature sorely lacking. The case is very roomy inside and even though it is not a full tower it really seems that big internally. All internal pieces are well laid out.
Construction is very sturdy and all mating pieces fit with good precision.
Removal of one thumb screw at the rear of the top cover is all that is required to get into the interior. The top slides off and the side panels lift easily away from the case. Installation is equally as easy. There are provisions for a front lower mounted fan and a rear fan below the power supply. The ATX power supply fan is correctly configured as an exhaust fan.
