A $175 Dell OptiPlex from Facebook Marketplace, running 24/7
Used Dell OptiPlex from Facebook Marketplace — $175, 16GB RAM, Linux Telegram as the interface (I barely touch the desktop app) Runs 24/7, no Mac Mini, no GPU rig … Every morning at 8:30am I get an email with 1-3 curated rental listings. It filters by school district, commute time, lighting, bedrooms, budget.
