Acer Aspire TC-875 D17E5
So, I have just become a concerned owner of a newer Acer computer. The model is included in the title. I want to upgrade this computer but I have some reservations on it. The motherboard is a custom solution for this build that has the USB C, the 3.0 USB and the audio jacks on the motherboard. Not only that but it only has an 8-pin for the power and a weird 6pin in place of your traditional 24pin connection. The PSU supplied to it is a SFF 300W of some kind and it looks like I have no room to upgrade? There are so many design choices here that I am unsure of and I am pretty close to sending it back as It looks like the upgrade path here is just non-existent. Any help would be nice or should I just return it?
