Not as good as this deal: https://www.ozbargain.com.au/node/765948 but there's a lot of useful info about the mobo, PSU, RAM etc in that post, and I encourage you to read the whole thing.
I upgraded the boot drive to a 2TB Intel 670p, added some SSDs and a 4TB 3.5" HDD I already had laying around, and I think it's a great, relatively smallish, work PC. Which can double as a gaming PC.
I haven't run emulators or played any games yet, but my workload is basically work shit—which can be pretty intensive—on a 4k 32", NBA playoffs on a 27" QHD, and OzBargain on a 24". Runs pretty quiet, fan ramps up occasionally but not often. Also got an optical drive and SD card reader. I bought a PCIe x4 card thing to attach the original 512GB NVMe drive and added an Asus wifi/bluetooth card to the other PCIe slot. The machine I received was very clean, with a legit service number you can look up on the Dell website, I updated the BIOS and drivers etc, and have been very happy since. I also got a tax invoice and 1 year warranty.
The only differences I can tell is that this one doesn't have an NVMe drive, Win 11 Home rather than Win 11 Pro, and only 3 months warranty. And costs a bit more.
s/o to @Genuine guy for the find
5 Gen old CPU, hm…
I assume the issues with Dell having proprietary components would make upgrading this rig unlikely?
So if the GPU, CPU, Psu fail, you need Dell to provide support which they may not for a 5 Gen old system?
