Initially, I went to those PC stores found in the local infamous computer malls for my highly customized desktop PC. I walked away disappointed with all these stores as they couldn't answer my technical questions professionally. All they were keen was to push whatever they have stocks on hand and didn't even fully comprehend the intrinsic value of every PC components. All their standard answers were:- "Dont worry, I sold many of these and have no problem". But, they don't understand is that I am not buying a component but a highly customized high performance system that requires proper system integration from casing to components. I decided to shop around those stores in shopping malls and instead do an internet search for reliable supplier with good review and rating. I found ByteSize. Over the phone, we discussed on my initial specification and my application. ByteSize was able to answer all my technical questions. After understanding my application and my needs, given that I am not using it for any gaming at all, ByteSize had recommended lower cost components to meet my requirements with convincing data by sending me technical specification accordingly including casing. Many of those shopping malls carries limited stock and would only push for those that they have on hand. But not for ByteSize. They would identify your needs first and match the right components accordingly with strong emphasis on what can and cannot upgrade in the future. So that I can make an informed choice or decision. Once those components are identified during initial technical discussion, ByteSize would do the following protocol and processes once confirmation is made:- -(1) Photos of all acquired components in their original packaging. Note that all these components packaging would be send together with the assembled PC. (2) During assembly process, ByteSize would wear ESD wrist stripe to protect all those highly sensitive electronic components particularly the CPU chipset. Those shopping malls' stores would touch and hold those sensitive electronic components with their bare hands and put on their working bench which is largely wood base without due consideration on proper anti-ESD work environment to prevent latent damage to those sensitive electronic components. (3) After assembly, to my surprise, ByteSize would carry out more than 24 hours burn-in test on the customized system to ensure every of those key components are performing to specification and more importantly, to test for proper integration and stability after all it's a highly customized system. Those PC stores in shopping malls does not carry out such test at all. (4) During the burn-in test, ByteSize would send the detailed test results for my review so that I know the status. After the test was completed, the full test result was also send out for my reference and assurance of no latent failure such as blue screen, sudden shut down, system freeze, over-heating etc. Such burn-in tests are mainly carried out in all major reputable OEM companies. (5) Free home delivery of my new toy with together with all the purchased components packaging. In other words, I just got my system online with any fuss and with the best technical support. After delivery, BtyeSize would check whether the PC is running smoothly and any issue encountered. Who does such a closed loop service for your after-sales service checking? The system was delivered to my home in March 2023. Now, is May2023 which I penned this review. I have been using these Desktop PC everyday 12hrs/day for 2 months without a single latent failure. It's highly stable and run at maximum clock speed. Ever since I have this desktop PC, I stopped using my Lenovo laptop which I bought in Aug2022. In short, the entire purchasing process from technical discussion to assembly and home delivery is just truly amazing which is so customer eccentric focus with strong technical professional service. It's a big thumbs up from me with 5 stars rating as it's very rare to find such professional service on very technical work.

Frequently Asked Questions (FAQs)

I can't decide on which parts I should get.

You will most often see the greatest performance benefits by focusing on your (i) Graphics Processing Unit (GPU); and (ii) Central Processing Unit (CPU) as these two components play the biggest roles in determining your overall system performance and capability. Next, you should ensure that you have sufficient RAM capacity for your applications.

Chat with us and we'll be more than happy to guide you in choosing the components that would best serve your needs for a Gaming PC and/or Workstation. 

What's the difference between Small Form Factor (SFF), Mid Towers and Full Towers?

Our Bytes are segregated into 3 different categories based on their physical dimensions in increasing order: (i) Small Form Factor (or commonly abbrieviated as SFF); (ii) Mid-Towers which utilise micro-ATX motherboards; and (iii) Full-Towers which utilise ATX motherboards.

SFF systems are suitable for users with physical constraints on the placement of their systems. It's advisable to add additional cooling to ensure sufficient ventilation for a SFF system due to their limited internal airflow.

Mid-Tower (micro-ATX) systems offers the greatest balance and flexibility between physical footprint and internal hardware components. Plus, they offer the best bang for your buck!

Full-Tower (ATX) systems are the ideal centerpiece of every gaming or workplace set-up. They sport the largest hardware compatibility and internal airflow for keeping the system cool under extreme and stressful conditions.

Do you provide all of the PC components boxes and packaging?

We certainly can! We use only brand new components in all of our Custom Gaming PCs, Desktops & Workstation builds. If you'd like to retain the PC component boxes and packaging do let us know when placing your order and we'll deliver the original packaging together with your system!
