So I have been trying to build a PC and have been following this guide. https://pcpartpicker.com/guide/DHTwrH/entry-level-amd-gaming-build. I have upgraded parts where necessary and created this build PCPartPicker Part List Type Item Price CPU AMD Ryzen 5 1600 (14nm) 3.2 GHz 6-Core Processor $85.00 Motherboard Gigabyte B450M DS3H Micro ATX AM4 Motherboard $72.99 @ Newegg Memory GeIL EVO SPEAR Phantom Gaming 16 GB (2 x 8 GB) DDR4-3000 Memory $64.99 @ Newegg Storage TCSunBow X3 480 GB 2.5" Solid State Drive $53.99 @ Amazon Video Card Gigabyte Radeon RX 570 8 GB GAMING 8G Video Card $139.99 Power Supply Corsair CXM 650 W 80+ Bronze Certified Semi-modular ATX Power Supply $94.99 @ Best Buy Prices include shipping, taxes, rebates, and discounts Total $511.95 Generated by PCPartPicker 2020-04-21 14:40 EDT-0400 . The only issue is the PC case. I plan on upgrading later on so I want space, but I need a pc case to fit my power supply. Any Suggestions on where to look or pc cases? My budget is around $50-$100
