Thanks all for the valid input!
The mini PC is defiantly a contender, as for 4K resolution. I'm just not sure.
Side note - here's a PC I found on eBay

Is it any good for that kind of money?
Let me know? Thanks!
Smith.
Sorry for the interruption, but as for me, Alienware is too expensive. You can buy two similar Acer-s or Asus-es for that price, am I right?How about this one?
I do a bit of gaming too so this could work
Love to know what you think!

, I think the processor and memory are also keys to have smooth operations with your pc. That is something you should also watch out for!You can handle 16 monitors for 800£.
You don't need too much power for a trading computer, unless you are going to do some crunching / programming / etc.
The question is what monitor size and resolution do you want ? A good 4K monitor on 28" today costs around 500£.
The stance to hold the screens is also very expensive so it depends whether you want to keep the screens on 1 row or 2 rows.

Then he should choose Mac with the Apple logo if it's so much important![]()
