I needed to replace an old Dell Precision laptop at the workshop and after browsing new workstations I found this place. PC Partpicker is an excellent resource and after some research I was able to put together a compatible parts list that would handle my work tasks. I had not built a PC before but the posts and guides here showed me the way. I now have a fairly compact PC that works well, looks good and was fun to build for less than the price of a pre-built tower. I'm also more knowledgeable about hardware and will be able to maintain and upgrade as required. This will be used for CAD, graphic design, photo editing, data-logging, and general office tasks. The graphics card is fine for my light CAD requirements.
Things I learned as a novice PC builder: Instruction books are basic or absent. Connectors are delicate (amazed I didn't break one). CPU coolers have strong springs so the board and CPU need to be carefully supported during assembly. Radeon Pro cards only have DisplayPort outs so need a cable with this at one end and HDMI at the other. Graphics card needed AMD software download for it to work. It's tempting to over-specify. It's genuinely satisfying when it fires-up.
I ran Cinebench and Unigine superposition out of curiosity but didn't know what to do with the results. It's a modest build and I won't be overclocking. I need a durable PC for work rather than top speed processing.
The Ryzen Master CPU software is an interesting insight. I tried Speccy first to check CPU temp and it worryingly read 75 C at idle while the Ryzen Master showed 28 C.
It took quite a lot of time for the whole process from research to final software installation so that's a cost but it's well worth acquiring the knowledge.
