I'm looking for a laptop with the following details:

1. Preferred Brand: any brand with good warranty and after sales service/support
2. Budget: RM3-4k
3. Usage: systems development
4. Preferred laptop/screen size: 14" FHD

I prefer laptops that don't get too hot under heavy stress and can be easily maintained/upgraded. I'm currently eyeing the ILLEGEAR RU-14 PRO, but their store is closed until Monday next week, and I need a laptop for work on that day itself. Yes, it's a last minute purchase.
