You will need to buy Speakers, a Wifi card (if you want to use WiFi although it does have a port for an ethernet cable and I prefer that because the speed is better), A webcam with a microphone, I don't use Bluetooth much but I had a dongle laying around so for snicks I plugged it in. and I picked up an extra 2 gig card to bring the memory up to four gigs. The computer is a little slow because it only comes with 2 gigs of RAM. Also, it's 32bit so four gig is your upper limit. I spent $40 total but that was because I wanted amplified speakers. I could have gotten away with under 40$ if not for that. (I don't like the windows software volume control). Everything worked great "out of the box". I wouldn't buy this system to play fancy video games but for email, facebook and youtube it does fine.
