Recommendation Requests

job acccept me 

I'm a first year betch cse student. I need a new laptop for coding and stuff. It's gonna be my first laptop so I'm super confused. I need something which i can use for like 5 years or more. Should have good battery life and a good processor i can use for coding 

I need a new gaming handheld. Something that is comfortable to hold. And supports streaming! 

I need a decent UPS. Something to keep my PC and Modem/Router online when I loose power.I'd love it if it has some sort of either remote management for notifications, or SSH. Not sure where to begin looking.

I need a decent cross compatible game controller. I mostly play PC but also have a PS5. Doesn't have to be a pro model or anything like that.

I'm looking for a good stand alone voice recorder. Something I can plop on the table and record meetings. And also something I can use to take quick voice memos with while I am out in the field.

I'm looking for a decent air purifier. Nothing too fancy, but I don't want a piece of junk. If you know what I mean. I'm willing to go up to 200$ I need something that can help with my allergies. It doesn't have to be big. I just need it for my office at work.

Im looking for a pair of reliable wireless earbuds under $50. My main priority is sound quality for listening to music and fit for working out. Good battery life at least 5 to 6 hours on a single charge is a must,please recommend options that durable and offer a stable Bluetooth connection. 

I would like to upgrade the storage available in a Synology DS416 4-bay NAS. It is already configured to use for business data storage as well as Time Machine backups. I'm looking for around 18TB of storage with 2-drive redundancy. What would the best hard drives be for this use case?
