If your buying in Hong Kong, why don't you just contact HK resellers to reserve one for you. For sure, they would want your business and you can even negotiate the price down or get some bonus items for free. They will have your PC done in short time and you just need to pick it up. They even offer services to build full custom loop PC's. You can message the seller through wechat/whatsapp. The site to look at is https://www.price.com.hk
. The contact numbers will be there also.
This is much better method than wasting your time walking through those computer malls. There's better stuff you can do with your time there. I don't really like the shopping experience in many of those malls (I've been to them for years and I prefer dealing with North American stores), they are just too crowded and its not comfortable buying things. If your going watercooling route, be aware Hong Kong has extemely limited selection of water cooling parts. Its bad enough, that my friends who watercool there have to order parts in from overseas.
For people helping you budget builds, please don't use US pricing. It is not relevant in Hong Kong. Usewww.price.com.hk
. From my experience there, you can get descent gaming rig for around 6000HKD or less (including windows).
On Side Note:
I recommend you guys go look at certain item pricing in Hong Kong like routers lol. Seriously, they are like 50-100% more than in North America. Everytime an router dies there (it happens to electronics because the weather is humid), I almost always have to buy an router here and bring it back to Hong Kong.
