Seeking an ideal online gaming build

Looking for help in buying a new desktop in the price range of £700 - £900 as even though ive spent many fun hours/years behind a plastic screen I ironically find myself at a loss as to what parts would work well together to achieve the result I am after (affordably).
Ideally the sort of gaming desktop I would be after;

- Would have enough space to contain the entirety of my steam account alongside a number of mmo's and still have some breathing space left over.

- Be able to handle extended periods of use on most games at a med-high setting (for example Skyrim, Sniper Elite V2, Lotro, Eso).

- Have access to Wi-Fi.

Any suggestions in that regard would be much appreciated :)

How many games/how much space does your steam account need? I've just finished download about 3/4 of my 246 Steam games (admittedly, that's most of the large ones) and it takes up over 1Tb of storage.

Quite the setup, my humble thanks :)

@Ricbai - The exact size in terms of memory allude me though its roughly 15-20 games linked to the account
