Put it on the floor, fan facing down, and attach with screws. Pull all the cables through the nearby hole in the motherboard tray, so you can easily route all the cables after you have all the other components in place.
Yes, three 140mm fans actually provide more airflow than needed for this setup. You can turn them all the way down to low RPM and enjoy a quiet PC that's still adequately cooled.
So, just in case, not for any specific reason? I'm pretty sure your use case of "web surfing, office documents, light gaming, music production" will never include any of
- Remote Desktop connections
- the ability to participate in a Windows Server domain
- Encrypting File System
- Hyper-V
- Virtual Hard Disk Booting
- Group Policy
- BitLocker and BitLocker To Go

Of course, it's entirely up to you, but I would still save the $30 because I'm 99% sure I'd never need any of these features. What I might need though is the ability install the OS on a different computer some time in the future - you can buy the non-Pro retail version directly from
Microsoft for $120. Retail allows reinstalling on another PC, while OEM is tied to the motherboard you first activate it on.
Precisely because of screen quality. Dell uses an IPS panel with more accurate colors and wider viewing angles than a low end TN-panel. It has a sturdy height adjustable stand, making it a more ergonomic choice. Dell's support and warranty is also great.
Well, the Asus monitor I linked is the next best thing in my opinion, as it's also an IPS panel, it's just a bit more cheaply built. So if you want to "cheap out" go with the Asus. Apart from the U2414H's 1" smaller cousing
P2314H, I couldn't find any better deals between those two monitors.
A headphone jack in a monitor...? Honestly I've never heard of such a thing. Just put headphones into the case's back panel or front panel header.
