Ideally panicking should always be done carefully.

That actually says "Escape Ladder", as in a fire escape.

Excellent wordery and nerdery. I look forward to possible future inclusions of birdery, absurdery, and cool-things-I-heardery.

I speak Mandarin, I can give it a shot.

CAN99 masks are super comfortable and have a rated 99% filtration rate. I highly recommend giving them a shot. They have both an earloop and a headstrap variety. My partner and I wear these every day, we haven't been sick in years, and they even help with our allergies and my partner's asthma. ☺️

It varies a LOT depending on the parts. Newegg is great for finding variety and its search/sort functionality is pretty good. Microcenter often has very good deals on parts, so that's not a bad plan. You could keep tab groups for each individual part to compare prices between different stores/sites.

Newegg also has a tool for assembling your PC, but definitely shop around for parts as there can be drastic differences in pricing. Waiting for sales and building it over time can save a lot in the long run. I haven't fully built a PC in a while, but I upgrade mine every 4-6 years. Ask me anything.😊
