DO NOT buy a dell prebuilt. they have limited upgradability.
proprietary motherboard and psu, cases are hotboxes.
and they use knock-off ram stick(s), if you even get dual channel.
You would be much better off with the lenovo.
some other websites to look at if you are going prebuiilt:
https://nzxt.comhttps://www.cyberpowerpc.comhttps://www.clxgaming.com/gaming-pchttps://www.ibuypower.comyou just have to watch the fine print a bit. and typically with ibuy/cyber you might want to have an different case handy. they tend to choke off the fans.
just do your research and take your time.
Appreciate it. I checked the links out and this one looks decent specs and in my budget.
