there is some ktard in kopitiam that builds custom pc as that is his actual day job
sometimes he will post pics of him building it maybe you can ask him
but if you ask for custom build and want the store to build it for you, the price may be the same as buying pre-built since the store will charge a fixing fee to fix it up for you which may or may not be cheap i.e. 10% fixing fee of your entire rig so if you buy 6k pc then its 600$ fixing fee
there are lots of ktards that love to build it for free for you but you'd be gambling on which one is sane and which one is insane
honestly building it your own is very satisfying but I can understand if you dont want to coz cable management is a pain in the ass and its actually a lot harder than what people say
so what you should do it compare the prices of custom + fixing fee and prebuilt
also, for 5k you can get the top 30% of the line specs. if top up 1k to 6k total you can get top 10% of the line
but you need to give more details on what you want to do with the pc before people can suggest something legit.
the one advice I'd give is dont cheap out on psu. I see lots of people suggesting no name brand psu but if you're gonna be powering a rtx 4090, im sure you want a reputable psu instead of a house fire right?

I saw from Microsoft website that it costs close to RM1k for it --> Source

So custom set tldr is diy set or self pick part then some1 assemble for u. Those "combo" or whatever package by shop 99.9% is custom, jz that the shop pick the part, some allow u to upgrade or down.

Prebuilt is like dell xpg u using , watever alienware crap system. Those are like they design a pc case , then fit watever crap in, sometime shit psu + ok gpu + no brand ssd etc. Some allow upgrade but still wont disclose what exact brand/model they using.

OS unless u using it to work in big corp environment then u buy from official. If home use jz buy those rm5 windows10 key from shopee/laz. Buy KEY CODE, not crack/file that activate.

No way 5k can get much nowadays. 3060ti alone also 2k already, i7 12th gen also almost 1.6k, mobo 1k. No money for good PSU good coolers.

Well, if you are retiring your old laptop or if it breaks down already, you may be able to reuse back the genuine windows key from it.. Since windows 10 windows key/license can be linked to your Microsoft account so when you are installing windows on new pc all u need to do is sign in the account and your Windows will be activated(assuming its the same version)..

Personally, my current pc is still using the original key from my old laptop(from 2010 if i remember correctly).. This is already my 3rd computer with same base windows key 

tak takut ke those keys from shopee etc - nanti susceptible to ransomware 

Those key is just 16 or more digit of code use to activate windows, u will get legit windows n update. Windows close one eye on this becoz they want more ppl to use the OS.

U can even use win xp or 7 activator to activate then upgrade to win10, but that another story.

You dont seriously think ur comp will get into trouble jz becoz u enter random 16digit into windows activation database right.

I was thinking more like in order for the Windows to work, a specific "version" of the Windows needed to be downloaded from the link provided by the seller - something like those pirated software.

I saw my friend bought a "licensed" Lightroom from a shoppee seller for RM5 that comes with "unlimited use" and upon payment, the seller gave a download link to which the application is downloaded - i cannot trust the life in me to have purchased software like this especially when i use my home computer to basically access everything to my life (banking etc) 

Nobody recommend that 1 ktard that always build PC and post drills in /k?? No jaga geng sendiri

Cannot remember his name, samjet or something

No way 5k can get much nowadays. 3060ti alone also 2k already, i7 12th gen also almost 1.6k, mobo 1k. No money for good PSU good coolers.

does Intel still have i5s?

my current XPS is running on i5 and it's ok for me - thought i7s are meant for multi-threading (or whatever they called it).
it's a home desktop and it's not broken down yet but it has been 7 years already and i feel an upgrade/replacement is nigh.

well, this is something new to me, i didn't know Windows OS is actually "transferrable". Aren't they bound to the PC that first installed them?

i got a little bit "inspired" on assembling my own after watching too many videos on building a system but given my history with electronics, i'm sure to break something expensive in between and i also know that building appears to be easy but can become very technical for newbies which is why i'm being cautious at the moment.

I want a gaming system that can accommodate High setting but if not, Medium for triple A titles will do just fine hence i'm referring the XPS's price as a budget gauge because my current XPS 8910 is acceptable to me.

Yeap, i've known all along that PSU cannot be cheap'd out - which is why the first thing that I tried to upgrade in my XPS8910 (before anything else) is actually the PSU but after finding out it's proprietary, i gave up.

I’ll say i7 and 1k mobo are still high end stuffs meant for bangsawan or those have too much money to spare.

Normies can live just as well with i5 and sub RM600 MOBO.

5000 budget can only get i5 and 3060ti meh, damn stupid prices leh. Personally I'd rather used 1080TI for 800 bucks la.

What graphics card do you have now, or your full current pc specs

Actually custom build PCs can be the best value per performance is because we actually buy the best price per performance(among all shops) parts and build ourselves.

It is not really a good value if you buy custom-built PCs as they tend to mark up the price a little, keep the extra cables/freebies for themselves and resell them, or selling near obsolete or low performance models and/or parts to you guys. (Not all shops though but 99%)

Just two cents from a guy who have built more than 20 PCs.

Not necessarily. Spec by spec, prebuilt sometimes can be worth it, it's the upgrade path that you lose out, upgradability like proprietary PSU or motherboard.

Example this Dell, selling 5.3k

https://www.dell.com/en-my/shop/pcs-desktop...=configurations

You go online spec this pc up yourself see can be cheaper than 5.3k or not. I7-12700, 3060ti, 2x8gb ddr5, 512ssd 1tb hdd, plus windows 11.
