Additionally, if you will be needing a lot of RAM, better go for the HP EliteDesk 800 G1 Tower as it has the ability to run 32 GB of RAM. The Dell Vostro 3669 can do a bit less at max 16 GB. Most of the times, this should be sufficient for the majority of users.
Ports
In total the HP EliteDesk 800 G1 Tower has 10 USB ports. The Dell Vostro 3669 is inferior in this regard and packs 6 USB ports. In any case, if you miss USB ports, you can always purchase a USB hub. None of the desktop models has a USB 3.1 port (10Gb/s), so if you need a fast connection to your peripherals, like external Solid State Drive, you will need to look elsewhere.
Unfortunately, only the HP EliteDesk 800 G1 Tower has a DisplayPort. The Dell Vostro 3669 does not have one? Don't worry though, nowadays video adapters are cheap and you can get almost any combination of conversion types.

Choosing either one depends on your specific requirements and use case. Also don't forget that some models might have more than one PSU option - try to always get the most powerful one, especially if you plan to upgrade to a powerful GPU.
