Well I just ordered a Proliant gen10+ microserver, as the gen10 of for 1/2 the price was the $0.59 hamburger (we ad it, but you can't order it). I also ordered 4 Seagate 4T terascale drives (seems nothing smaller around). So in some 2 weeks I will have it all together and will see what happens when I do the install. :) Supposedly there is an internal boot usb port in the gen10+ On 1/6/23 09:42, Robert Heller wrote: > At Fri, 6 Jan 2023 08:39:22 +0100 CentOS mailing list <centos at centos.org> wrote: > >> Hi >> >>> I have found a: >>> >>> HPE 873830-S01 ProLiant MicroServer Gen10 >>> >>> for <$300 without drives. If I can believe the seller, it has a AMD >>> Opteron X3216 Dual-core (2 Core) 1.6GHz and 8GB Installed. >>> >>> It has 4 3.5" bays. and 1?
