I bought the Canakit Pi 4 Starter Kit (4GB) with the clear case. I also have the Canakit Pi 3 with clear case.The kit is easy to assemble, just be careful with the fan wiring and position it to blow air into the case.All the parts snap together very easily. The fit is secure with no wobbles and take-apart is also easy.The case top is easy to remove for access to GPIO pins.The power supply is rated at 3.5v Amps and I can connect a 1TB NVMe SSD via USB 3 with no issues (it uses USB 3 power from the Pi).Running a 100% CPU load stress test results are shown below - no thermal throttling occurred.I installed NOOBS and ran the full update of Raspian Buster which took a bit of time (depends on internet speed).I was using the home WiFi and the setup detected it with no problems.I installed a few pieces of software like Fritzing and Sysbench, etc., with no issues.I connected Chromium to my Google account and all my bookmarks synced.I installed KeePass 2 (a password manager) and exported my main computer database and imported it with no issues.Browsing YouTube and watching videos is quite acceptable in performance and response.Then I formatted a second MicroSD card with the Full Raspian image using Etcher and installed it just for fun.Boot time is very short and I can copy from my home directory on the Pi to the other SD card via a USB SD reader/writer (for backups).I have not used Ethernet yet, nor the audio port.Pros:Very small, inexpensive, and fast. A complete single board computer that snaps together in minutes.The fan is very quiet and prevents excessive heat from throttling the CPU.If you have used Linux before you will feel right at home.Cons:You will need to make the NOOBS installer on a microSD card separately.The fan connector gets in the way of a GPIO cable connector, so you may want some sort of Fan Shim if this is an issue,or maybe get a fanless cooling case like the Flirc Raspberry Pi 4 Case (I have no experience with that, I just heard good things about it).Flirc case at Amazon:https://www.amazon.com/Flirc-Raspberry-Pi-Case-Silver/dp/B07WG4DW52-----------------------------------------------------------------------------Stress test script I used - Canakit case and fan with standard NOOBS install:----------------------------------------------------------------------------#!/bin/bash# Stress test CPU# Jim Hurley# version 1.0# 24 Aug 2019# to install sysbench: sudo apt-get install sysbench#cleardateecho "Starting stress test ..."#stress test the CPU - 4 threads, factor primes up to 25000, 10 timesfor counter in `seq 1 10`do date echo "Test start" $counter vcgencmd measure_temp # show temperature sysbench --test=cpu --cpu-max-prime=25000 --num-threads=4 run >/dev/null 2>&1 echo "Test done " $counterdoneecho "... stress test over"echo $datevcgencmd measure_temp=============== output text ============================================================Sat 24 Aug 2019 06:31:51 PM PDTStarting stress test ...Sat 24 Aug 2019 06:31:51 PM PDTTest start 1temp=46.0'CTest done 1Sat 24 Aug 2019 06:33:18 PM PDTTest start 2temp=59.0'CTest done 2Sat 24 Aug 2019 06:34:45 PM PDTTest start 3temp=61.0'CTest done 3Sat 24 Aug 2019 06:36:12 PM PDTTest start 4temp=61.0'CTest done 4Sat 24 Aug 2019 06:37:38 PM PDTTest start 5temp=62.0'CTest done 5Sat 24 Aug 2019 06:39:05 PM PDTTest start 6temp=63.0'CTest done 6Sat 24 Aug 2019 06:40:32 PM PDTTest start 7temp=63.0'CTest done 7Sat 24 Aug 2019 06:41:59 PM PDTTest start 8temp=64.0'CTest done 8Sat 24 Aug 2019 06:43:25 PM PDTTest start 9temp=63.0'CTest done 9Sat 24 Aug 2019 06:44:52 PM PDTTest start 10temp=64.0'CTest done 10... stress test overtemp=63.0'C
