Selling our HP 8300 USDT (ultra-small desktop). These things are pretty awesome for home-lab purposes. Really powerful for the price, and low power usage as well.

• 2.9 core i5-3470s
• Graphics: HD2500
• 6.6 cm x 25.1 cm x 25.4 cm
• 500 GB spinning disk
• 2GB RAM (two slots, could probably find some ram for it for free)

Only downside is no power supply.

Looking for $30, happy to post at buyer's expense.
