It’s there a slot for a discrete graphics card? Can I upgrade with internal wireless? Thanks.
No discrete GPU option – the entire computer is just over 1L in volume. There is a M.2 E-key slot for a 2230 WLAN card, but if these were not originally equipped as such, the wiring for the antennas may not be included.
There are more details at Dell Support:

There is no wiring for antennas so whichever WLAN card you buy must include the antennas.
Be a bit careful though because these items don’t appear to be “refurbished” - they include (at least the one I got) non Dell parts in configurations that Dell does not use. I spent the extra money for the one with 32Gb of memory and the 1TB SSD.
If you buy this from Dell with only one drive, then it will be a M2 drive. The one I bought came with a no-name 2.5 inch SSD. The memory is also non-Dell spec memory - both of these will slow the computer.
These are (when you buy them from Dell or a properly refurbished computer) great computers - tiny and very robust.
With the no-name parts, these are a very iffy proposition. As an aside, and this is kind of unimportant as most everyone who buys something like this has a spare keyboard and mouse - the one that comes with these is a really inexpensive combo ($8.95 including shipping on AliExpress) and the wi-fi dongle is a 802n USB 2.0 - under $10 at Amazon - so both virtually useless.
Again, “refurbished” means that it has the same specs as when it left the factory.
