If you're not gaming you can build a computer for super cheap. Lower that budget to around $750, get a nice looking case (something aluminum or from Corsair), get an i3/APU for CPU, proper motherboard with the connections you need, reliable 450W power supply (i.e. Antec earthwatts), small 64GB SSD for booting, and lots of storage hard drives, which is dirt cheap (last storage HDD sale was two days ago, $100 for 3TB Toshiba drive) and you should be good to go. Spend the extra money on a new pair of phones or something.
There's also the ultimate in compactness: the Intel NUC http://www.intel.com/content/www/us/en/nuc/overview.html
~$650 on Newegg will get you an i5 model, 16Gb RAM, and a 120Gb mSATA drive. another $34 would add wireless capability
