Actually come to think of it, when i travel to BKK anually to visit my relatives, i will drop by at Prathunam Pantip Plaza (Their version of SLS) and walk around. There quite concentrate a lot on DIY PC.
In fact the OEM brands are loosing out over there to DIY. Not sure why but every corner i go i rarely see any shop selling OEM PC. They sell Pre made DIY PC. Which is imo cheaper than the OEM PC. But no OS. One has to go source out for their own OS.
The buying power of the local people there isnt strong, mostly could not afford OEM PC as they are quite expensive. And usually they very rare to come out low end models for the poor to afford. I barely seen any OEM PC that offers like Pentium or Celeron base PC. And worse their service centre is not in BKK city itself. Some are outside of BKK and take days or weeks for service man to service it.
Unlike SG. Many are still buying OEM PC. Making DIY PC a smaller market demand. Only enthusiast or existing owners that uses DIY PC will reconsider to buy components from SLS. Other than that after doing much quotation for Forumers whom wanna get a DIY PC, only a handful are new to DIY PC.
So it still boils down on how DIY PC shops or Distro marketing it.
