Acer looks fine though. The Dell XPS stuff will obv be nicer but you'll probably need to find a student discount and some good luck to get it towards 650. Otherwise Inspiron, Acer etc will all be decent.
Acer's lack of detailed specs on its site is maddening.
Currently looking at an Aspire 5 A514-54 that I can get for ~£600. 8GB RAM (can upgrade to 20GB myself at a later date). 512GB SSD. 14" screen (don't want bigger). i5-1135G7 CPU.
Can drive a 4K monitor over HDMI 2.0 and probably not USB-C (which would have been preferred) but finding any accurate specs is nigh on impossible.
Cheapest Dell that meets my requirements is £1000, even with various sales/outlets.
