Saw their price memang high a bit but not absurdly high la. They also keep a lot of variety, u can build anything with them.

Im not related to Idealtech. But dust cleaning stuffs should be done by owner , it just like cleaning your house aircond filter. Not much difference , maybe you need to remove your casing side panel and blast air into it using a blower. You dont need to dismantle anything if you think you are not confident in doing that. A blower cost you like 100~200 bucks if you buy from Shopee or Lazada which you can offset from their higher prices compare to certain shops in lowyat or maybe e-tech in kepong.

Your psu warranty replacement thing actually good already la . Normally other shops i claim warranty need 1 week plus , worse case close to 3 weeks. Bcoz the replacement unit actually comes from distributor , not from their existing new stock. Most shops will never use their new stock to replace warranty units.

What to do with a non operational rig for the weekend ? Thts the real reason why ppl buy prebuilts like HP, Dell and Lenovo bcoz they have next business day onsite warranty. If you so urgent to use your rig , you shouldnt even consider buying DIY builts in the first place.

~ just my 2 cents worth
