If you are looking for a simple, low power consumption 12volt computer this little guy is a dream. You can use this in the house with 120 with the wall wart it comes with, but you can also just wire it up for a straight 12V connection for a car, truck, or RV. This system is by no means a gaming computer, but will handle the casual computer users tasks such as email, word processing and web browsing. If you try to do more, the poor little CPU will max out and be pegged at 100 and not work very well. As a Ham Radio operator using Yaesu System Fusion and WiresX - this little gem married with an internet connection is a great node radio computer! WiresX software runs perfectly on it. Recommend buy for simple use for sure.
