  1   ATXCASE040    P4 ATX MID TOWER CASE 300 WATT            95.00     95.00
                    power supply .

                     No manufacturer is shown, the box
                    says made in China; parts list shows 30
                    components numbered according to an
                    assembly diagram.

                    There are extra I/0 Panel parts, possibly
                    to replace the installed panel if it is
                    somehow damaged.

                     Case has a fan mounted inside the
                    front panel, in addition to the heat sink
                    fan for the CPU. This fan blows hot air and
                    dust from inside the case outside an
                    exhaust register in the back panel of the
                    case.  The Quick Reference for the D850GB
                    main board shows on page 19 in para 11 an
                    explanation for connecting fans.

                     The case is shorter, but wider than other
                    cases.  This makes it easier to install
                    equipment,particualarly in the dirve bays.

                     Side panels are installed first, and
                    clip into slots, then slide down into the
                    final position.  The top cover slides
                    horizontally forward to hold the side
                    panels in place.  There is only a single
                    large headed screw that holds the top cover
                    in place.

                       did this.

                       requires a special AGP circuit board
                       with a "retention notch" at the end.

                    This is installed with clips on top of
                    the CPU.  There is an extra set of
                    installation clips.

                    Tony showed there are two banks of
                    128 RDRAM installed.  There are two
                    more banks that can accept 128 MB
                    RDRAM Chips, and these are filled with
                    a temporary component that must be
                    installed in any memory slot that is
                    used for actual RDRAM.

                    Raul said when I called this morning
                    that the ATI Fury Pro he quoted would
                    not support the D850GB main board, so
                    PC Doctor substituted a higher performance
                    video card at no extra charge.

                     This may reflect comment on page 7 of
                    Quick Start Quide that explains the AGP
                    video card must have a special slot.

                    (D850GBAL only)

                     Since we have the D850GB, this requirement
                    seems not to apply.
