Very unhappy with the XPS 8950 purchase. I will never buy another Dell computer.Purchased the XPS 8950 on 17/03/2022 and the computer was supposed to arrive on 08/04/2022 but it ended up arriving on 22/04/2022 "due to high demand" according to Dell. When I tried to install the second 3.5" hard drive from my old computer, I found that there is no spare hard disk tray caddy inside the second hard disk bay. So I ordered the 3.5" hard disk bracket with SATA cable from Dell's website for NZ$14.15.This is the only 3.5" hard drive bracket from Dell's website and so I thought it must be the one I need and ordered it even though it doesn't have a photo. It turns out that it is a metal hard drive enclosure and doesn't work for my secondary hard drive. The SATA cable doesn't work as well because XPS 8950 needs a SATA cable with right angle connector in at least one end with an orientation opposite to the common ones I can buy from computer shops.So I call Dell and the Dell Support says they would help me to find the right parts and give me a quote. I got the quote a couple of days later and it was NZ$120.03 which is ridiculous for a plastic hard drive tray caddy and SATA cable. I refused to pay for that ridiculous price and modified my previous hard drive tray caddy to install the second hard disk and used a temporary SATA cable but I still cannot close the cover of the computer because the connector is not right angle.Lessons learnt:- Don't trust Dell's estimated delivery date. Don't buy from Dell if you need it urgently. When you call them, they would simply tell you that there is delay due to high demand and ask you if you want to cancel the order. I would have cancelled the order if I knew about the delay earlier but I missed other vendors' End-of-EY discount offers already by the time I knew about the delay.- Dell's computers (at least my XPS 8950) require proprietary parts that you cannot easily buy from normal computer shops - even something as simple as a SATA cable.- Dell's proprietary parts could be a lot more expensive than other vendors. A cheap plastic HD tray caddy and a SATA cable could cost $120 - I would expect something like $14 that I paid for the wrong parts from them.- Dell's common parts are not available on their website. Quite a few parts on their website have no photos at all and so don't assume it is the right parts unless you have double checked with Dell Support. Question: How hard is it for Dell to put photos on the online shopping website for all their products?Think twice before you buy anything from Dell.
