Utopia, Dream, Fantasy.
You can typewriter. Well, for reading email. there will be enough books.

You can also try. i5 2400, 16 GB ddr3, gf 1050 2gb, ndd 500 GB

There is enough for a 10th generation Intel processor, motherboard, memory, disk.
Profitable DNS Kits - Intel Core i5-10400 BOX.
All that remains is the case and the power supply.

I'm afraid if this processor is included in the assembly, there won't be enough money for everything else.

depending on for what purposes and what the current
PeKa, but pushing forward the pitch for modern games, it is better to immediately retreat with 400 dollars

Favorable set of dns (i3 10100 OEM processor, without F at the end - there will be built-in graphics. If you find a video card, then -2000r. for 10100F you can save):
Spoiler
SSD 120GB for work is enough. You can 1Tb HDD (but there will be no benefit) or 240GB SU 650 + 1000r. You add CoolerMaster MWE 500 WHITE - V2 [MPE-5001-ACABW] for 3800, and ID-Cooling SE-224-XT cooler for 2200, DEEPCOOL GAMMAXX 300 - 1500r or 213v2, 400ex.
Everything, you assemble it with an open stand and work with the built-in, later you select the video card and case. Deepcool MATREXX 55 MESH case. With video cards, in any case, the trouble is on the market.
You can consider b / y or ali with his huanan (google, the same is cheap). If an office, then a used 1600/2600 risen will go with the A320, but it does not have an installation (the main thing is for reasonable money, no more than 10, ideally thousand. 7.
There are ready-made assemblies in stores for the office, it is difficult with them If the game, then this is rubbish.
It is possible and much better if you take a wool used market and are ready to bargain.
Ali has kits - X99 DDR4 2 DIMM D4 LGA2011-3 with Xeon E5 2620 V3 Sor 1 piece * 8 GB for 15 thousand
rubles.Atermiter X79 Turbo motherboard, LGA2011, ATX Combos E5 2689, CPU 4 pcs. X 4 GB = 16 GB, DDR3 RAM 1600 MHz, PC3, 12800R, PCI-E, NVME, M.2 SSD for 12 ty.Or
separately from here the mat. fee and take 2630v2. In short, calculate and decide.
The video card is definitely to trade on the used market, the main thing is that the condition and the price are more or less.
With Ali the cheapest pc + time to check. Google the topic, if the budget is tight, then only used and ali together. And on a used video card will remain, some kind of more than 1060/6

without vidyahi on the installation only if, where you can run in cops and dotku and fortnight in 40 frames
and assemble with a reserve for a future gradual upgrade,
or buy a BU assembly, which you can play here and now, but after 2 years you need to assemble on a new one

for what pc, for games and what kind of game? for movies and TV shows, surfing the Internet or for work, what kind of work again?

for building bu x99 can still be adequate with a normal processor. x79 is already a little like this, but with 6 turf it can go. the problem is that for this or that one needs the correct RAM of at least 32GB and it will not be possible to install new processors on a number of boards if a bare board is sold there and it is not flashed, so this is a very notable smut. but it's kind of a corn 1600-1700 still relatively peppy and having fewer problems with ozu compatibility.
the whole upgrade will rest on the video card for games, but for me, for example, 2060s is not enough, so the processor does not really decide at the moment.
