New PC build to replace old Dell XPS. Probably my last computer. Suggestions appreciated.

[Srfoot]

Hi;
I want to replace an old Dell XPS win 7 which has become too slow.
I use it for e-mail, Quickbooks, internet, burning DVD's, home network, no games.
I'm going to go with Win 10. Thinking of intel i7. 1T HD, memory 16? DVD burner.
I use an external HD attached for backup, home NAS, scanner, networked printer, need enough USB ports, monitor,etc.
Under $900.00.
Not sure of processor, motherboard,case,etc.
Will probably be my last computer,
Thank you for all suggestions.
Or, is there a premade computer I should consider which might be a better value?
Thank you!

It may be that the system is just in need of some TLC.
When did you last defragment the HDD?
When did you last clear out the various internet caches and .Temp files that are so liberally scattered throughout Windows?
Do you regularly have many internet tabs or apps open at once? If so the system may be running out of RAM, if it does so it'll automatically use the HDD as extended memory which can result in all sorts of glitches.
Is anything overheating? The CPU and graphics card ( if any ) will throttle-slow down-if they get too hot, again leading to dramatic performance loss.
Maybe all that is needed is a RAM upgrade and/or the addition of an SSD to speed things up.
Maybe.

Which system would be suitable for your uses depends on the home network: If it's transcoding a lot of video it'll need a beefy CPU, if not a lesser part will get the job done easily enough.
For the other uses any half decent Quad cored CPU with 16Gb of RAM will be more than enough.
