what do I do???

Chey
So my partner is turning 18 soon and I don't know what to get him!!! He is so hard to buy for cause he never knows what he wants... so what's some ideas for a present? He likes computers more than anything but every game I have gotten for him he doesn't play so I'm not going to spend another $150 (New Zealand Dollars) on a game he isn't going to play. But I'm open to any ideas! Please please please I'm so stuck
