i don't know where you got the idea of me not being experienced enought to test my system's stability when i never said anything other than "i've used arch for 3+ years" but if my machines are what you are interested in, i'll tell you.

i've ran arch for 3+ years on:

1. [2014-2016] i5-4690 + msi h81m-p33 + evga gtx 760 sc acx + 2x4 gskill ripjawsx + 1tb 7200rpm wd10ezex
2. [2016-2017] intel atom n455 + igpu + 2gb generic ddr2 + 32gb usb2.0 for storage (no hdd)
3. [2017-2017] athlon64 3800+ + generic hp mobo + 1gb kingston ddr2 800 mhz + ati radeon xpress 1550 + 1tb 7200rpm wd10ezex
4. [2017-2017] athlon64 5200+ + generic hp mobo + 4x1gb kingston ddr2 667 mhz + ati radeon hd 6350 + 1tb 7200rpm wd10ezex
5. [2017-2018] c2d e8400 + biostar g31-m7 te + ati radeon hd 6350 + 2x2gb ddr2 800mhz + 1tb 7200rpm wd10ezex
6. [2018-2018] xeon e5450 + biostar g31-m7 te + g31 igpu + 2x2gb ddr2 800mhz + 1tb 7200rpm wd10ezex
7. [2018-2018] xeon x3430 + ibm x3100 server board + onboard aspeed gpu (couldn't even display the color red) + 4x2gb ecc samsung 1333 mhz + 1tb 7200rpm wd10ezex
8. [2018- current] pentium g3258 + msi h81m-p33 + haswell gt1 igpu + 2x4gb corsair vengeance ddr3 + 1tb 7200rpm wd10ezex

these are all the machines i've owned since april 2014, i've used arch with them until i moved over to gentoo at the summer of 2018. i also can link you the scripts i used to maintain and install my systems alongside with the configs i used to compile my custom kernels.
