I have only ever sold two items via eBay (and they were for about $20 each) but I am wondering if it is possible to claim my iMac that I purcahsed last year as a tax expense? I am a full time student, but can't claim it as an education expense because I am yet to start working in my field. 

I know the chances are slim, but I'll take the deductions where I can! 

Any help would be appreciated.
