You're gonna have to invest into Photoshop.
I've had worse setup than this and a simple contrast increase can solve the problem for mass editing.
If you just take a few pictures, Photoshop has a tool to easily cut out the products, and then you can turn the background to completely white.
 
Also set your White Balance on the camera to one setting, preferably indoor light, don't put it on Auto White Balance.

If you want perfectly clean on-white images, best is to shoot the product on gray or suspended with clamps/arms/prongs/on-plexi/whatever (so the surface doesn't reflect as much light or color into the product), make a custom white balance to neutralize color and nail your highlights and shadows using a gray card like an X-Rite Colorchecker. Then in post do a clipping path in photoshop and knock it out. Drop a shadow of whatever shape/size is appropriate, and that will let you save the image on any color or shade of surface, be it white, red, even transparent so it can be comp'd onto graphics for ads.
 
The way you're shooting the product is fine, you don't have any real lighting control with those ebay tents, but at minimum it'll give you a clean enough starting point where knockouts and dropshadows are a reasonable next step.
 
I also suggest outsourcing that post-work. It's extremely time-consuming and there are many outlets online who can turnaround hundreds of products within a day or two for cents per image. That's what the big agencies do...

For equipment, what you're using should be just fine. Honestly you don't need high end stuff to do this.
Camera should be locked down on a tripod, ISO 100, 1/200th, f/5.6 or f/8, f/11 at max.
You might need to back the camera out a few feet to get more depth of field, and get the whole product in focus.
Don't stop down to f/16 or f/22, diffraction will just make the whole image softer, f/11 will be about as tight as you can go without obvious softness.
 
If you're using continuous lights, make sure you turn off all other inside lights, like overhead fluorescents. This is to control color temps and spill that might be happening. That will help make colors and tones look more uniform. If you're using strobes, they should be bright enough to overpower the ambient light. Either way whatever type of light you use, for this specific case, shouldn't matter all that much so long as you have control. 
 
Also, when you do your drop shadows, you need to make sure they're making sense. The drop shadows need to closely match the real shadow from the photo. You can even paint the old shadow back in if you want more realism. 
 
Are you shooting these objects from overheat, or propped up? If they're propped up, that shadow should be below the product, not directly behind it like a halo. If it's overhead, make sure the shadow is going in a singular direction. A drop shadow directly behind the subject, giving it a halo, is like what you get out of a ringlight, but the light on the subject doesn't match that, so that's why it doesn't make sense and looks off. 
 
Highlights on the product make it look like these are mostly lit from above, so your shadows should be following that same direction and falling below the subject. 
 
Again, you can use something like Fiverr to outsource this kind of stuff. otherwise it's kind of a major time suck. 

This is totally subjective non-expert feedback, but as an average-joe, the pictures with the gray outline really hurts my eyes. It gives me the impression that I have not focused correctly and my eyes are constantly trying to "focus on the image" 

This is simple and others are over complicating it.
 
Shoot your images in a raw format with a sane amount of lighting (those examples above are reflecting way too much). Open said images in Photoshop, magic wand or whatever other selection technique you want, use the refine selection tool and cut the subject. Drop the subject layer on top of a contrasting color layer like red or green and feather the edges. You’re working with black and white so this will be extremely easy. Adjust levels, contrast, whatever and save it with a transparent background for flexibility in future placement.  
Simple. Selection in Photoshop is super easy and among the first things you should learn. Watch a YouTube tutorial and you’ll get the hang of it in 20 minutes.

Those look great! Edges look super clean and the contrast/brightness is right where you want it. Good work!

I think it looks great now, lighting seems to be spot on to me. 

@For Science!Hi, thanks for the input and sorry for the late answer, I did end up removing the shadow halo completely, you are totaly right it looks much better and cleaner. When I first added the halo shading there, it looked good (but I must note that I saw it at work on a pretty good monitor). When I checked the photos from home on my ordinary laptop the edges of the product were really blurry. Thanks for the tip!

^When I can actually easily recommend someone to fully use their old Corsair board as a macro board
With Corsair keyboards (that support iCUE), you can change any key to any other key, so you can easily set up some easy macros for stuff you do often
 
P.S. nice choice on keycaps; purple/lavender is highly underrated!

Ah, that's too bad. Starting off with great pictures always helps a lot.
But to be honest, I think if you guys get the opportunity to redo the leftmost picture (the 3D model render), this picture can come out looking a lot better.
The three photos on the right actually line up decently well (it's just that the left-most photo I made a bit too small, lol ), it's mainly the 3D render that's at a significantly different angle.
That might be the easiest one to get ahold of the project file and redo the screenshot!
I'm always happy to help!

Linus' server room, circa 2016 (colorized)

Hi guys, I need some advice.
 
I work in a small company (5 people in the office). We need new computers. I would like to have our workstations located on the second floor of our building in the server closet, we have plenty of rack space, and we would use the heat from the computers to heat the adjacent warehouse. Therefore we would not waste it, and we wouldn't need as much AC in the office below. Something like Linus's home setup. What is the best way to achieve that for a reasonable price? Four of us need two monitors (1080p 60Hz) and some USB ports for mouses and keyboards. I use three monitors (one 1440p 60Hz and two 1080p 60Hz), 3D mouse, two keyboards (one for macros), El gato stream deck xl for macros and one more port for a USB thumb drive.
 
EDIT: I forgot to mention how long the cables need to be. They need to be 15-25 meters long

Hit me with ideas guys.
